Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Rate law is always written according to the slowest step and thus exponents for concentrations do not necessarily match the stoichiometric coefficients.

Hence, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
