JEE Main Chemistry question

Which of the following statements is **incorrect** about the molecularity of a reaction? [OJEE 2007]

(A)Molecularity of a reaction is the number of molecules of the reactants present in the balanced equation
(B)Molecularity of a reaction is the number of molecules in the slowest step
(C)Molecularity is always a whole number
(D)There is no difference between order and molecularity of a reactionCorrect

Answer: (D)

Solution

Molecularity, defined for an elementary step as the number of reacting species (molecules/ions/atoms) taking part in that step, is always a positive whole number, and for a single-step (elementary) reaction it is given by the molecules in that (slowest) step — statements (A), (B) and (C) are
