The aim of this experiment is to find out and study how temperature has an effect on the rates of reaction. I am going to investigate the changes caused to the solution of hydrochloric acid and sodium thiosulphate when the temperature is increased.

Rates of Reactions Aim: The aim of this experiment is to find out and study how temperature has an effect on the rates of reaction. I am going to investigate the changes caused to the solution of hydrochloric acid and sodium thiosulphate when the temperature is increased. Prediction: A chemical reaction can only occur between particles when they collide. Particles may be atoms, ions or molecules. There is a minimum amount of energy which colliding particles need in order to react with each other. If the colliding particles have less than the minimum energy, then they just bounce off each other and no reaction occurs. The minimum energy is called the activation energy. Temperature: Increasing the temperature makes the particles move more rapidly. This means that more particles collide with each other per second. Also, the more rapidly the particles are moving, the greater is the proportion of them which will...
