Question

Which of the following statements is incorrect regarding order of reaction and molecularity?Select the proper choice from the given choices.
(A) Molecularity is the theoretical conclusion while order of reaction is experimental conclusion.
(B) The value of molecularity is positive integer while the value of reaction order may be positive, negative of zero.
(C) Molecularity explains the reaction mechanism while reaction order does not give any information about reaction mechanism.
(D) For elementary reactions, the order of reaction and rnolecularity are same.

Answer 1

Answer:

Statement b

Explanation:

Answer 2

The incorrect choice in the given options is (C) Molecularity explains the reaction mechanism while reaction order does not give any information about reaction mechanism.

Statement (A) is correct, since molecularity is only theoretically driven based on an equation of chemical equilibrium. Statement (B) is correct, because while molecularity can only have positive integral values, order can take any value including fractions. Statement (C) is incorrect, since order provides information about the mechanism of a reaction. Statement (D) is correct, since elementary reactions have same order and molecularity.
