Problem

For the equilibrium

\mathrm{CO(g) + 2\,H_2(g) \rightleftharpoons CH_3OH(g)}

at 500 K, the equilibrium constant is

K_p = 2.3

. A sealed container at 500 K contains partial pressures

P_{\mathrm{CO}} = 4.0\,\text{atm}

P_{\mathrm{H_2}} = 5.0\,\text{atm}

, and

P_{\mathrm{CH_3OH}} = 0.20\,\text{atm}

. Determine

Q_p

for the mixture and predict the direction of the net reaction as it approaches equilibrium.
