question 27

Multiple Choice

A 3.50-mol sample of HI is placed in a 1.00-L vessel at 460°C, and the reaction system is allowed to come to equilibrium. The HI partially decomposes, forming 0.266 mol H₂ and 0.266 mol I₂ at equilibrium. What is the equilibrium constant K_c for the following reaction at 460°C?
½ H₂(g) + ½ I₂(g) $\rightleftharpoons$ HI(g)
