Increasing the temperature can have a significant impact on the rate of a photochemical reaction involved in the formation of ozone from oxygen molecules. The formation of ozone  O3  from oxygen molecules  O2  is a three-step process:1. Photodissociation: A high-energy ultraviolet  UV  photon breaks an oxygen molecule  O2  into two oxygen atoms  O .O2 + UV photon  2O2. Association: An oxygen atom  O  reacts with an oxygen molecule  O2  to form ozone  O3 .O + O2  O33. Dissociation: Ozone absorbs UV radiation and dissociates back into an oxygen molecule and an oxygen atom.O3 + UV photon  O2 + OThe overall reaction is:3O2 + UV photon  2O3The rate of a photochemical reaction depends on the number of collisions between reacting molecules and the energy of these collisions. Increasing the temperature increases the kinetic energy of the molecules, which leads to more frequent and energetic collisions. This, in turn, increases the rate of the reaction.However, it is important to note that the formation of ozone is primarily driven by the availability of high-energy UV photons, which are not directly affected by temperature. The rate of photodissociation  step 1  depends on the intensity of UV radiation, and this step is usually the rate-limiting step in the formation of ozone.In summary, increasing the temperature can increase the rate of the ozone formation reaction by increasing the kinetic energy of the molecules and the frequency of collisions. However, the overall rate of the reaction is primarily determined by the availability of high-energy UV photons, which are not directly affected by temperature.
