Question

A reaction at 300 K with Δ G ° = -3486 J consists of 2 moles of A(g), 4 moles of B(g) and 4 moles of C(g). If A, B and C are in equilibrium in a 1 L container, then the reaction may be (ln 2 = 0.7, R = 8.3 J/K/mol)

TestHub · Accepted Answer

ln K = 3486/(8.3 × 300) = 1.4 = 2ln 2, so K = 4 Concentrations in 1 L: [A] = 2 M, [B] = 4 M, [C] = 4 M

(a) K = (4)²/(2 × 4) = 2

(b) K = (4)(4)/(2)² = 4

(c) K = (4)(4)²/2 = 32

(d) K = 4/(2 × 4) = 0.5

Only (b) gives K = 4, so the answer is option (b).
