Rate of reaction Aim: The aim of this investigation is to find out and observe how temperature affects the rate of reaction. I am going to investigate the changes caused to the solution of hydrochloric acid and sodium thiosulphate when the temperature is changed. Prior Knowledge/Research: The rate of reaction is the speed or velocity at which a chemical reaction precedes, expressed in terms of the amount of product formed or the amount of unitīs time taken for a certain reaction to occur (usually in seconds). Thus for the reaction of two compounds (in this case X and Y) that form a product (Z) the equation would be: X+Y=Z The Rate of Reaction varies greatly. Some chemical reactions, such as explosions, happen very quickly while others like rusting, occur very slowly. The rate of reaction can be affected by a number of factors: temperature, concentration and pressure, adding a catalyst, surface area/particle size and light. The...
