Hattie Sparks 10F 22nd June 2002 Chemistry Sc1 Investigating the effect of temperature on rate of reaction Aim: to determine if changing the temperature of the sodium thiosulphate will alter the rate of reaction Introduction: The rate of reaction is the measure of the change that happens in a single unit of time. In this investigation I am going to try and determine whether altering the temperature of the sodium thiosulphate does alter the rate of reaction, using the collision theory this should be true. However, many other things could alter the rate of reaction, such as: 1. Volume of acid/solution 2. Concentration of solution The equation for the reaction is: Na2S2O3 + 2HCl 2NaCl + S + S02 + H2O From this equation I can determine the products, and consequently what I can measure to calculate the rate of reaction. I am going to use the production of sodium chloride, a precipitate. As collecting sulphur oxide is dangerous,...
