Investigating The Factors Affecting The Rate Of A Chemical Reaction.

Investigating the factors affecting the rate of a chemical reaction.

Introduction:
In my coursework I will be mainly concentrating on the reaction between dilute hydrochloric acid with marble chips (calcium carbonate).
Calcium carbonate (marble chips) + hydrochloric acid ==> calcium chloride + water + carbon dioxide
CaCO3(s) + 2HCl (aq) ==> CaCl2 (aq) + H2O (l) + CO2 (g)
Aim:
The aim of the experiment is to investigate how the concentration of hydrochloric acid affects the rate of reaction with marble chips, i.e. how quickly/how much hydrogen is produced.

Firstly I would like to establish the term ‘rate of reaction', the term means how fast a reaction occurs it could also mean in other aspects how slow the reaction occurring takes place.
There are a number of factors that determine the rates of reaction, listed below are the factors affecting the rate of reaction:
(a) the solution concentration,
(b) the temperature of the reactants,
(c) the size of the solid......
