Which of the following statement(s) is/are correct for a photochemical reaction? — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Photochemical reactions generally involve multi-step radical mechanisms (initiation, propagation, termination). The initiation step relies on photon absorption (intensity), making it zero-order with respect to reactant concentration. The overall reaction rate depends directly on the intensity of absorbed light. Therefore, correct answer is A,C,D.
