AIPMT PRELIMS 2010 Chemistry Rate Laws MCQ Question
Type: MCQ-conceptual-Medium-Class 12
During the kinetic study of the reaction 2A + B → C + D, following results were obtained:
A
rate = k[A][B]²
B
rate = k[A]²[B]
C
rate = k[A][B]
D
rate = k[A]²[B]²
Correct Answer
Option A
Detailed Explanation
By comparing the rates and concentrations, it can be deduced that the reaction is first order with respect to A and second order with respect to B. Therefore, the rate law is rate = k[A][B]².
