Yurii V Geletii

Yes, if the formation of the reactive species is the rate limiting step

Mohamed E. El-Halwagy

Thx dr Yurii... One more question is it a bad sign of the incapability of catalyst to form the reactive species??

It depends. It might be good because the degradation rate does not decrease in the course of reaction

Thx again Dr. Yorii your quik response is highly appreciated 😊
