Q153. For the synthesis of ammonia via the Haber process, N2(g) + 3H2(g) ⇌ 2NH3(g), which expression correctly represents the equilibrium constant, Kc? Assume the initial moles of N2 and H2 are 'a' and 'b' respectively, 'x' is the moles of N2 that have reacted at equilibrium, and the reaction occurs in a container of volume 'V'.Chemistry — NUST Mock By IBAGRADS 1 — Question 153 of 200A. Kc = x2 / ((a-x)(b-x))B. Kc = x2 / (V(a-x))C. Kc = 4x2 / (V(a-x))D. Kc = 4x2V2 / ((a-x)(b-3x)3)Practice more Chemistry MCQs for entrance exam preparation on Examora.io.← Previous Question Next Question →
