Question

Rate constant "k" for a certain reaction is k = $2.3 \times 10^{-5}$ $L$ $mol^{-1}$ $s^{-1}$. Order of the reaction is:

• A. 0
• B. 1
• C. 2
• D. 3

Answer 1

Answer: (C)

2

Answer 2

$K = 2.3 × 10^5$ $L$ $mol^{-1}$ $s^{-1}$

For order of reaction,

The unit $L$ $mol^{–1}$ $s^{–1}$ corresponds to the 2$$nd order reaction.

Hence, the correct option is (C): 2
