STANDARD Chemistry Rate of Reaction MCQ Question

Type: MCQ-conceptual-Medium-Class 12

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

A

2k'

B

k' = 2k

C

k' = k

D

k = 14k′\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.
