Which molecules are more likely in the course of a collision to reach the transition state and overcome the activation energy barrier to form products - those that have a violent collision (high velocities and kinetic energies) OR those that have a gentle collision (low velocities and kinetic energies)? Explain your reasoning. Is a violent collision more likely to occur at lower temperatures or higher temperatures? The rate of a chemical reaction approximately doubles for every 10°C rise in temperature. Explain this phenomenon and what you think is happening. (Hint : think about what effect increasing temperature has on the individual molecules.)
