Sulphur Clock Investigation. There are many factors that influence the rate of a precipitation reaction. For example: 1. Temperature. 2. Surface Area. 3. Pressure. 4. Concentration. 5. The effect of a catalyst. However I have chosen to study the influence of temperature on the reaction. I believe that if you increase the temperature at which the reaction is working, then the speed of the reaction will increase. This means, therefore, that: The speed of the reaction will increase, due to the collision theory. When heated, molecules gain kinetic energy from the original heat source. This enables them to move faster and will therefore, collide more often. I have reason to believe my prediction is true as I have found relevant secondary information, which I found while doing some background reading. There are two reasons why reactions go faster as the temperature rises: * The particles collide more often. * The particles collide with more energy, so more collisions result in a...
