What is the equilibrium expression for the reaction \( \mathrm{P}_{4(\mathrm{~s})}+5 \mathrm{O}_{2(\mathrm{~g})} \rightleftharpoons \mathrm{P}_{4} \mathrm{O}_{10(\mathrm{~s})} \) ?
(A) \( \mathrm{K}_{\mathrm{C}}=\left[\mathrm{P}_{4} \mathrm{O}_{10}\right] /\left[\mathrm{P}_{4}\right]\left[\mathrm{O}_{2}\right]^{5} \)
(B) \( \mathrm{K}_{\mathrm{C}}=\left[\mathrm{P}_{4} \mathrm{O}_{10}\right] / 5\left[\mathrm{P}_{4}\right]\left[\mathrm{O}_{2}\right] \)
\( P \)
(C) \( \mathrm{K}_{\mathrm{C}}=\left[\mathrm{O}_{2}\right]^{5} \)
(D) \( \mathrm{K}_{\mathrm{C}}=1 /\left[\mathrm{O}_{2}\right]^{5} \)
