To answer this question, we need to know the specific chemical and the specific wavelength of light involved in the photochemical reaction. However, I can provide a general explanation of how temperature can affect photochemical reaction rates.In general, increasing the temperature can have several effects on photochemical reactions:1. Increased molecular motion: As the temperature increases, the molecules involved in the reaction will have more kinetic energy, leading to more frequent and energetic collisions between reactant molecules. This can increase the likelihood of successful reactions, thereby increasing the reaction rate.2. Enhanced absorption of light: Higher temperatures can lead to a broader absorption spectrum for the reactant molecules, allowing them to absorb a wider range of wavelengths. This can increase the number of molecules that are excited by the specific wavelength of light, leading to a higher reaction rate.3. Altered reaction pathways: Increasing the temperature can change the reaction pathways available to the reactant molecules. Some pathways may become more favorable at higher temperatures, leading to a faster overall reaction rate.4. Increased rate of side reactions: Higher temperatures can also increase the rate of side reactions, which may compete with the desired photochemical reaction. This can either increase or decrease the overall reaction rate, depending on the specific system.It's important to note that the effect of temperature on photochemical reaction rates can be complex and depends on the specific chemical system under study. To determine the exact effect of temperature on the photochemical reaction rate of a specific chemical under a specific wavelength of light, experimental data or computational modeling would be required.
