Soloha48 [4]

Answer:

Kc=\frac{[HI]^2}{[I_2][H_2]}

Explanation:

Hello there!

In this case, for these equilibrium problems it is firstly necessary to know the balanced reaction at equilibrium:

H2((g) + I2(g) ⇋ 2HI(g)

Next, by means of the law of mass action, it turns out possible for us to write the required and correct expression for the equilibrium constant by considering the concentrations and the coefficients in the aforementioned reaction:

Kc=\frac{[HI]^2}{[I_2][H_2]}

Best regards!
