A gas mixture is prepared in a rigid container at a temperature at which the reaction

\(\text{X}_2\text{(g)}+\text{Y}_2\text{(g)}\rightleftharpoons 2\text{XY(g)}\)

has \(K_p=2.0\). The total pressure of the mixture is \(8.0\text{ atm}\), and each molecule pictured in the diagram represents the same number of actual molecules.

Which choice correctly gives the reaction quotient, \(Q_p\), for the mixture and predicts the direction of the net reaction?
