WebbThe difference in the reaction speed is a result of the differences in activation energy for the controlling step. For chain polymerizations, the rate determining step is the initial initiation step, but the polymer forming step has a low activation energy, generally between 2 to 10 kcal/mole. WebbThe iodine clock is a two-step reaction as outlined below: In the first, slow reaction, iodine is produced: H X 2 O X 2 + 2 I X − + 2 H X + I X 2 + 2 H X 2 O. In the second, fast reaction, iodine is reconverted to 2 iodide ions by the thiosulfate: 2 S X 2 O X 3 X 2 − + I X 2 S X 4 O X 6 X 2 − + 2 I X −.

"WebbAs the intensity of light increases, the particles absorb more energy and hence the rate of reaction increases. For example, when methane reacts with chlorine in the dark, the reaction rate is slow. It can be sped up when the mixture is put under diffused light. In bright sunlight, the reaction is explosive.
