AIPMT MAINS 2011 Chemistry Rate Laws MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The rate of the reaction 2N₂O₅ → 4NO₂ + O₂ can be written in three ways: -d[N₂O₅]/dt = k[N₂O₅], d[NO₂]/dt = k'[N₂O₅], d[O₂]/dt = k''[N₂O₅]. The relationship between k and k' and between k and k'' are
A
k' = 2k; k'' = 2k
B
k' = k; k'' = k
C
k' = 2k; k'' = k
D
k' = 2k; k'' = k/2
Correct Answer
Option D
Detailed Explanation
The stoichiometry of the reaction gives k' = 2k and k'' = k/2 based on the coefficients of NO₂ and O₂ in the balanced equation.
