• For the reaction :

1/2 H₂(g) + 1/2 I₂ (g) ⇋ HI (g) K_c = [HI] = 5 (given)

For the reaction

H₂(g) + I₂ (g) ⇋2HI (g) , ) K_c = [HI]² = (5)² = 25

Hence, for the reaction 2HI (g) ⇋ H₂(g) + I₂ (g) , the value of K_c will be = = 1/25 = 0.04.

At 500 K, Equilibrium constant, Kc, for the following reaction is 5.1/2 H2(g) + 1/2 I2 (g) ⇋ HI (g)What would be the Equilibrium constant Kc for the reaction2HI (g) ⇋ H2(g) + I2 (g)

At 500 K, Equilibrium constant, K_c, for the following reaction is 5.
1/2 H₂(g) + 1/2 I₂ (g) ⇋ HI (g)

What would be the Equilibrium constant K_c for the reaction

2HI (g) ⇋ H₂(g) + I₂ (g)
