The effect of different light intensities on the reaction rate of the photochemical decomposition of hydrogen peroxide can be explained through the principles of photochemistry. The decomposition of hydrogen peroxide H2O2 into water H2O and oxygen O2 can be accelerated by exposure to light, particularly ultraviolet UV light. The reaction can be represented as:2 H2O2 2 H2O + O2In photochemical reactions, the reaction rate is directly proportional to the light intensity. As the intensity of light increases, the number of photons light particles that interact with the hydrogen peroxide molecules also increases. This leads to a higher probability of the hydrogen peroxide molecules absorbing the photons and undergoing decomposition.Therefore, as the light intensity increases, the reaction rate of the photochemical decomposition of hydrogen peroxide also increases. However, this relationship is not linear, and the reaction rate may not continue to increase indefinitely with increasing light intensity. At very high light intensities, other factors such as temperature and the availability of hydrogen peroxide molecules may become limiting factors, causing the reaction rate to plateau.In summary, increasing light intensity generally leads to an increased reaction rate of the photochemical decomposition of hydrogen peroxide, up to a certain point where other factors may limit the reaction rate.
