AIPMT MAIN 2008 Chemistry Arrhenius Equation MCQ Question
Type: MCQ-numerical-Hard-Class 12
The rate constants k₁ and k₂ for two different reactions are 10¹⁶ · e⁻²⁰⁰⁰/ᵀ and 10¹⁵ · e⁻¹⁰⁰⁰/ᵀ respectively. The temperature at which k₁ = k₂ is
A
2.303 K
B
1000 K
C
2000 K
D
2000 K
Correct Answer
Option A
Detailed Explanation
Setting k₁ = k₂ gives the equation 10¹⁶ · e⁻²⁰⁰⁰/ᵀ = 10¹⁵ · e⁻¹⁰⁰⁰/ᵀ. Solving for T gives T = 1000/2.303 K.
