The rate of reaction depends on how often and how hard the reacting particles collide with each other particles have to collide in order to react, and the have to collide hard enough as well marble chips hydrochloric acid essay rates of reaction essay research paper rates. - the rate of reaction between hydrochloric acid and marble chips plan in this experiment, i will be investigating the rate of the reaction between hydrochloric acid (hcl) and marble chips to do this, i will change the concentration of the hcl and measure how that affects the amount of co2 produced. Transcript of rates of reaction: hcl & marble chips the effect of concentration on reaction rate environmental sciences essay the reaction of marble chips with hydrochloric acid is first order with respect to hydrochloric acid method in this experiment there will be different variables. When the large marble chips are added to the hydrochloric acid the rate of reaction will be slower resulting in less gas being produced this is because the large marble chips have a smaller surface area this means that it will be quicker with the smaller marble chips to produce 100cm3 of carbon. Introduction this chemistry investigation was performed to investigate the rate of reaction between marble chips (calcium carbonate - cacl ) and hydrochloric acid (hcl) in this investigation i want to find out whether the concentration of hydrochl.
As the marble chips got larger, the reaction with acid was slowed until the size of the chips reached a point the rate of reaction aim:to investigate how different concentrations of hydrochloric aci9d affect the rate of reaction on marble chip, (calcium carbonate. This is an heterogeneous reaction as far as we know the acid reacts on the surface of the marble if the marble chips are ground up, their particles size is reduced, and their surface area (and the rate) is increased on the other hand, an increase in temperature usually elevates the rate. Marble chips and hydrochloric acid the aim of this experiment is to find the factors that affect the rate of reaction between calcium carbonate and hydrochloric acid.
Rates of reaction: marble chips and hydrochloric acid rates of reaction planning aim to find if changing the concentration of an acid will increase or decrease the rate of the reaction when marble is dissolved in hydrochloric acid. Investigating the rate of reaction between marble chips and hydrochloric acid planning i will use marble chips and different concentrations of introduction i am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area. The final reaction should look something like the below diagram: measuring cylinder water glass tube co2 hcl tank marble chips results 1 molar 08 molar time mean volume of co2 rate of reaction gradient time mean volume of co2 rate of reaction gradient 10 12 12 10 9 09 20 22 11 20. I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction i predict that when i have a higher concentration i will have a faster rate of reaction referring to edexcel science revision guide edited by mary james, the collision theory.
The purpose of this experiment is to discover the reaction rate in which acid rain weathers marble statues, or in our case, marble chips multiple factors can impact on the rate of the reaction between the acidic factors and the marble particles these are stated below. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ scientific knowledge: marble chips erode when they are exposed to acid rain or pollution erosion is evident when you look at older marble buildings. 5 grams of marble chips into the conical flask as well and time the rate of reaction between the two my results show a steady in crease in the rates of reaction between hydrochloric acid and marble chips this happens because the weaker the concentration of hydrochloric acid the fewer. When the large marble chips are added to the hydrochloric acid the rate of reaction will be slower resulting in less gas being produced this is because the large marble chips have a smaller surface area.
Introduction we are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid i will add calcium carbonate (marble chips) to hydrochloric acid when calcium carbonate is added to hydrochloric acid a reaction takes place. The rate of reaction depends on how often and how hard the reacting particles collide with each other however, the gas given off was too much for the gas syringe so i changed it to 2g of marble chips and 5cm cubed of hydrochloric acid. The essay on marble chip investigation the rate of reaction making my results less accurate although the marble chips were roughly the same size they weren't all exactly means that there is very little chance of acid particles colliding with the marble chip with enough energy to react. Concentration varies directly with the rate of reaction aim: to investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials : conical flask/glass jam jars, measuring cylinder, stop clock/watch with seconds/stop watch app, direct reading balance, dilute. Rates of reaction: hydrochloric acid & marble chips the experiment the aim of this experiment is to find out how different variables affect the rate at 3 catalyst 4 surface area exothermic reactions this reaction between marble chips (calcium carbonate) and hydrochloric acid is an exothermic.
Rates of reaction - marble chips and hcl in this experiment, marble chips, or calcium carbonate (caco3), will be dropped into a flask containing hydrochloric acid (hcl) the reaction is: caco3(s) + 2hcl(l) -- cacl2 + h2o(l) + co2(g. Home gcse applied science rates of reaction - marble chips/hydrochloric acid a chemical that speeds up reactions without being used up itself lowers the amount of activation energy/ temperature needed, saving money on fuel.
Hold the marble chips in when weighing variables: i will change the different concentrations of hydrochloric acid to produce a wide range of results as we are testing the effect of concentration on the rate of reaction. Reaction between marble chips and hydrochloric acid my prediction for this experiment is that as the concentration of hydrochloric acid increases, the rate of reaction will also increase in direct proportion my reasons behind the above prediction are that so a reaction can take place, the particles of the.
Add some marble chips to hydrochloric acid in a conical flask with a side arm and draw attention to the gas evolved issue mini whiteboards take in the rate of reaction graphs sheet write comments or questions to highlight the achievement that has been demonstrated. The size of the marble chips (floor section) and concentration of hydrochloric acid might the two have a power on the value of the reaction if the marble chips are the comparable length and the concentration of acid used is persevering with, then neither might strengthen by making use of.
