Statement: In rate laws, unlike in the expression for equilibrium constants, the exponents for concentration do not necessarity match stoichiometric coefficients. Explanation: It is the mechanism and not the balanced chemical equation for the overall change that governs the reaction rate.

Answer»

(a) `S` is CORRECT but `E` is wrong
(B) `S` is wrong but `E` is correct
(c ) Both `S` and `E` are correct and `E` is correct explanation of `S`
(d) Both `S` and `E` are correct but `E` is not correct explanation of `S`.

Solution :Reaction rate is experimental quantity and not NECESSARY depends on stoichiometric COEFFICIENTS.
