Equilibria — practice question

Nitrogen dioxide, $\text{NO}_2$, is in equilibrium with dinitrogen tetroxide, $\text{N}_2\text{O}_4$. $2\text{NO}_2(g) \rightleftharpoons \text{N}_2\text{O}_4(g)$, $\Delta H = -57\text{ kJ mol}^{-1}$ Which conditions lead to the largest percentage of $\text{N}_2\text{O}_4(g)$ at equilibrium?
