For a complex (multistep) reaction, — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

For a complex reaction, the slowest step is rate-determining. Molecularity applies only to elementary steps, so overall molecularity has no meaning. Order is experimental and may differ from molecularity. There can be multiple slow steps acting as rate-determining steps under certain conditions. Therefore, correct answer is A,B,C,D.
