As shown in Table \(15.2, K_{p}\) for the equilibrium

\(\mathrm{N}_{2}(g)+3 \mathrm{H}_{2}(g) \rightleftharpoons 2 \mathrm{NH}_{3}(g)\)

is \(4.51 \times 10^{-5}\) at \(450^{\circ} \mathrm{C}\). For each of the mixtures listed here, indicate whether the mixture is at equilibrium at \(450^{\circ} \mathrm{C}\). If it is not at equilibrium, indicate the direction (toward product or toward reactants) in which the mixture must shift to achieve equilibrium.

(a) \(98 \mathrm{~atm} \mathrm{} \mathrm{NH}_{3}, 45 \mathrm{~atm} \mathrm{} \mathrm{N}_{2}, 55 \mathrm{~atm} \mathrm{} \mathrm{H}_{2}\)

(b) \(57 \mathrm{~atm} \mathrm{NH}_{3}, 143 \mathrm{~atm} \mathrm{} \mathrm{N}_{2}\), no \(\mathrm{H}_{2}\)

(c) \(13 \mathrm{~atm} \mathrm{} \mathrm{NH}_{3}, 27\) atm \(\mathrm{N}_{2}, 82 \mathrm{~atm} \mathrm{} \mathrm{H}_{2}\)
