NEET Chemistry Rate of Reaction Assertion Reason Question
Assertion (A): The molecularity of the slowest step in a reaction mechanism equals the overall reaction order. | Reason (R): The order of a reaction is always determined by the stoichiometric coefficients of the reactants.
Both (A) and (R) are true, and (R) is the correct explanation of (A).
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
(A) is true, but (R) is false.
(A) is false.
Correct Answer
Detailed Explanation
The molecularity of the slowest step does determine the order of the overall reaction (A is true), but the order of a reaction is an experimental quantity and is not always determined by stoichiometric coefficients (R is false).
