Reversible reactions and equilibrium — practice question

Dinitrogen tetroxide, $\text{N}_2\text{O}_4$, changes into nitrogen dioxide, $\text{NO}_2$, through a reversible reaction. $\text{N}_2\text{O}_4(g) \rightleftharpoons 2\text{NO}_2(g)$ The forward reaction is endothermic. Which conditions result in the greatest equilibrium yield of nitrogen dioxide?
