Q. Which of the following statements are correct? 1. Order of a reaction can be known from experimental result and not from the stoichiometry of reaction 2. Overall molecularity of a reaction may be determined in a manner similar to overall order of reaction 3. Overall order of reaction, ${\ \ \ A}^{m} + B^{n} \rightarrow AB_{x}\$is$\ (m + n)$ 4. Molecularity of a reaction refers to (i) Molecularity of each of the elementary steps (slow steps) in a multistep reaction (ii) Molecularity of that particular step in a single step reaction Select the correct answer by using the codes given below
A) 1, 3 and 4
B) 1, 2 and 3
C) 2, 3 and 4
D) 1, 2 and 4
Explanation
(d)
$A^{m} + B^{n} \rightarrow ABx$
In this case,
Overall order of reaction $= m + n$
Hence, code 3 is wrong
