Problem

At 298 K298\,\text{K} the equilibrium constant for the reaction 2 HI(g)⇌H2(g)+I2(g)2\,\text{HI}(g) \rightleftharpoons \text{H}_2(g) + \text{I}_2(g) is K=1.3×1010K = 1.3 \times 10^{10}. State whether the equilibrium mixture will consist predominantly of reactants, products, or comparable amounts of both.
