NEET 2025 Chemistry Equilibrium Constants MCQ Question
Type: MCQ-numerical-Medium-Class 11
For the reaction A(g) ⇌ 2B(g), the backward reaction rate constant is higher than the forward reaction rate constant by a factor of 2500, at 1000 K.
[Given : R = 0.0831 L atm mol⁻¹ K⁻¹] Kₚ for the reaction at 1000 K is
A
83.1
B
2.077 × 10⁵
C
0.033
D
0.021
Correct Answer
Option C
Detailed Explanation
The equilibrium constant Kₚ is calculated using the relation Kₚ = Kc(RT)^(Δn). Given the factor difference, Kₚ is determined to be 0.033.
