Question

A mixture of H2 and I2 is allowed to react at 676 K. H2(g) + I2(g) ⇌ 2HI(g) The initial concentration of the reactants are [H2] = 0.2260 M and [I2] = 0.2470 M. After the system reaches equilibrium, it is found that the I2 concentration has decreased to 0.0605 M. Based on these data, determine the value of the equilibrium constant, K, for this reaction.
