STANDARD Chemistry Rate of Reaction MCQ Question with Solution

Consider the reaction: 2N₂O₄ ⇌ 4NO₂ If $\frac{d[N_2O_4]}{dt} = k$ and $\frac{d[NO_2]}{dt} = k'$ then

A

2k'

B

k' = 2k

C

k' = k

D

k = $\frac{1}{4}k'$

Correct Answer

Option B

Detailed Explanation

The rate of formation of NO₂ is twice the rate of decomposition of N₂O₄. Therefore, k' = 2k.
