NEET Chemistry Chemical Equilibrium MCQ Question

Type: MCQ-numerical-Easy-Class 11

For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g) at 500 K, if the equilibrium constant Kc is 0.061 and the concentrations are [N2] = 3.0 mol L–1, [H2] = 2.0 mol L–1, and [NH3] = 0.5 mol L–1, what is the reaction quotient Qc?

A

0.041

B

0.061

C

0.081

D

0.101

Correct Answer

Option A

Detailed Explanation

Qc is calculated as [NH3]^2 / ([N2][H2]^3) = (0.5)^2 / (3.0 * (2.0)^3) = 0.041, which is less than Kc, indicating the reaction will proceed forward.
