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.
