NEET Chemistry Chemical Equilibrium MCQ Question
For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g) at 500 K, the equilibrium concentrations are [N2] = 1.5 × 10^-2 M, [H2] = 3.0 × 10^-2 M, and [NH3] = 1.2 × 10^-2 M. What is the value of the equilibrium constant Kc?
55 × 10^2
0.355
55
0.355 × 10^-2
Correct Answer
Detailed Explanation
Using the formula Kc = [NH3]^2 / ([N2][H2]^3), substituting the given concentrations yields Kc = (1.2 × 10^-2)^2 / ((1.5 × 10^-2)(3.0 × 10^-2)^3) = 3.55 × 10^2.
