Question

Statement I : Equilibrium constant is the ratio of the product of molar concentrations of the products to the product of molar concentrations of reactants with each concentration term raised to the power equal to the respective stoichiometric coefficient in the balanced chemical equation.\ Statement II : The equilibrium constant for the reaction\ 
$\mathrm{CaSO}_4 \cdot 5 \mathrm{H}_2 \mathrm{O}_{(s)} ightleftharpoons \mathrm{CaSO}_4 \cdot 3 \mathrm{H}_2 \mathrm{O}_{(s)}+2 \mathrm{H}_2 \mathrm{O}_{(g)}$ is\ $K_c=\frac{\left[\mathrm{CaSO}_4 \cdot 3 \mathrm{H}_2 \mathrm{O}ight]\left[\mathrm{H}_2 \mathrm{O}ight]^2}{\left[\mathrm{CaSO}_4 \cdot 5 \mathrm{H}_2 \mathrm{O}ight]}$.

(b) : $K_c=\left[\mathrm{H}_2 \mathrm{O}\right]^2$, because concentration of solids is taken to be unity.
