For the system A (g) + 2 B (g) C (g) the equilibrium concentrations are A = 0.06 mol L–1 B = 0.12 mol L–1 C = 0.216 mol L–1. The Keq for the reaction is
A.250✓ Correct
B.416
C.4×10–3
D.125.
Explanation
Reaction A(g) 2B(g) C(g) At equil 0.06M 0.12M 0.216M c 2 [C] 0.216 K = = =250 0.12×0.12×0.06 [B] [A] Hence, the correct answer is option (a)
