Write the expressions for $K_{P}$ and $K_{C}$ for the reaction: $3Fe_{(s)} + 4H_2O_{(g)} \rightleftharpoons Fe_3O_{4(s)} + 4H_{2(g)}$.

(N/A) For the given reaction: $3Fe_{(s)} + 4H_2O_{(g)} \rightleftharpoons Fe_3O_{4(s)} + 4H_{2(g)}$.
$1$. The expression for $K_{C}$ is given by the ratio of the molar concentrations of products to reactants,raised to the power of their stoichiometric coefficients. Pure solids are excluded from the expression as their activity is taken as $1$.
$K_{C} = \frac{[H_2]^4}{[H_2O]^4}$
$2$. The expression for $K_{P}$ is given by the ratio of the partial pressures of gaseous products to gaseous reactants,raised to the power of their stoichiometric coefficients.
$K_{P} = \frac{(P_{H_2})^4}{(P_{H_2O})^4}$
