Consider the equilibrium between $N_2O_4$(g) and $NO_2$(g).

Consider the equilibrium between $N_2O_4$(g) and $NO_2$(g).

$N_2O_4(g) \rightleftharpoons 2NO_2(g) \quad ΔH = +58 \, \mathrm{kJ \, mol^{−1}}$

Which changes shift the position of equilibrium to the right?

I. Increasing the temperature

II. Decreasing the pressure

III. Adding a catalyst
