Question

15 moles of H 2 and 5.2 moles of I 2 are mixed and allowed to attain equilibrium at 500 o C . At equilibrium, the number of moles of H I is found to be 10 mole. The equilibrium constant for the formation of H I is, 50, 15, 100, 25

MARKS App · Accepted Answer

H 2 + I 2 ⇌ 2 H I 15 5.2 0 15 − 5 5.2 − 5 10 Equilibrium constant K c = H I 2 H 2 [ I 2 ] = 10 × 10 10 × 0.2 = 50
