Chemistry Coursework: rate of reaction Tom Burgess Aim: To investigate how changing the temperature affects the rate of reaction between sodium thiosulphate and hydrochloric acid. Background information: The rate of reaction is the formation of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: temperature, concentration, pressure (in gases), surface are, and catalysts. The explanation for a chemical reaction involves the idea of collision. For particles to react they have to collide with enough energy, so not all collisions are successful. To speed up a reaction you must increase the number of collisions and the energy that the collisions have Small surface area: Larger surface area: Formula: Preliminary experiment: In class we did a background investigation where instead of changing the temperature, which is what...
