Question

Which of the following statements is correct?
(1) order of a reaction can be known from experimental results and not from the stoichiometry of a reaction.
(2) molecularity a reaction refers to (i) each of the elementary steps in (an overall mechanism of) a complex reaction or (ii) a single step reaction.
(3) overall molecularity of a reaction may be determined in a manner similar to overall order of reaction.
(4) overall order of a reaction $A^m+B^n⟶A{B}_x$ is $m+n$ Select the correct answer using the following codes:

• A. 2 and 3
• B. 1,3 and 4
• C. 2,3 and 4
• D. 1,2 and 3

Answer 1

Answer: (D)

The stoichiometric coefficients of reaction has no relation to the order of reaction.
