The equilibrium constant for the reaction: H2(g) + I2(g) —> 2HI(g) is Kc = 54.H2(g) + I2(g) 2 HI as it proceeds toward equilibrium.Since kf and kr are constants, the ratio of kf divided by kr must also be a constant. This ratio is the equilibrium constant for the reaction, Kc. The ratio of the concentrations of the reactants and products is known as the equilibrium constant expression.
