STANDARD Chemistry Order of Reaction MCQ Question
Type: MCQ-numerical-Medium-Class 12
For a reaction X → Y, the rate of reaction becomes twenty seven times when the concentration of X is increased three times. What is the order of the reaction?
A
2
B
1
C
3
D
0
Correct Answer
Option C
Detailed Explanation
Let rate of reaction R = k[X]ⁿ. When concentration is increased three times, 27R = k(3X)ⁿ. Dividing gives 27 = 3ⁿ, solving for n gives n = 3.
