In order to get maximum marks in this coursework it is vital that you discuss all factors which affect the rate of a reaction these include: temperature. When temperature is increased the particles move faster and with more energy, therefore the collisions happen more often and with more force so the reaction is faster four factors which affect rates of reaction: surface area - surface area is the measure of how much exposed area a solid object has. Factors affecting the rate you will be expected to remember the factors that affect the rate of reactions, and to plot or interpret graphs from rate experiments how to increase the rate of a reaction. Rates of reaction what is the effect of raising the temperature on the rate of a chemical reaction raising the temperature will increase the rate of a chemical reaction because 1 raising the temperature makes the particles move faster this means that the particles collide more frequently with each other and the rate of the reaction increases 2 the faster the particles are moving, the.
Gcse chemistry coursework: investigating the rate of a reaction your task is to plan, and carry out, an experiment to discover how to change the rate the reaction between sodium thiosulphate solution and dilute hydrochloric acid. Rates of reaction the rate of a reaction can be measured by the rate at which a reactant is used up, or the rate at which a product is formed the temperature, concentration, pressure of reacting gases, surface area of reacting solids, and the use of catalysts, are all factors which affect the rate of a reaction.
