INVESTIGATING HOW TEMPERATURE AFFECTS THE RATE OF REACTION BETWEEN SODIUM THIOSULPHATE AND HYDROCHLORIC ACID Aim: The aim of this experiment is to investigate how temperature affects the rate of reaction between sodium thiosulphate and hydrochloric acid. Theory: Through the knowledge which I have attained through previous experiments exploring how collisions between particles vary with different temperatures, I have come to the theory that the rate of reaction between sodium thiosulphate and hydrochloric acid will increases with heat. When temperature is increased, particles move faster and this leads to more successful collisions. When the number of successful collisions is higher, the rate of reaction is faster. Fig. 1: Fig. 2: Figure 1 shows a reaction at a low temperature. The particles are moving slowly so there are not very much successful collisions. Figure 2 shows a reaction at a higher temperature. There are more successful collisions because the particles are moving faster. The balanced equation for...
