Dinitrogen tetroxide decomposes reversibly into nitrogen dioxide in an endothermic reaction:

N2O4(g)⇌2NO2(g)ΔH=+57 kJ mol−1 \text{N}_2\text{O}_4\text{(g)} \rightleftharpoons 2\text{NO}_2\text{(g)} \quad \Delta H = +57\text{ kJ mol}^{-1} N2​O4​(g)⇌2NO2​(g)ΔH=+57 kJ mol−1

Which change decreases the equilibrium yield of NO2\text{NO}_2NO2​ but has no effect on the value of the equilibrium constant KpK_{\text{p}}Kp​?

Decrease the temperature of the system

Increase the total pressure of the system at constant temperature

Add a catalyst to the mixture

Increase the volume of the reaction vessel at constant temperature
