Carbon monoxide reacts with hydrogen in the following exothermic reaction to produce methanol:
CO(g)+2H2(g)⇌CH3OH(g) \text{CO(g)} + 2\text{H}_2\text{(g)} \rightleftharpoons \text{CH}_3\text{OH(g)} CO(g)+2H2(g)⇌CH3OH(g)Which change increases the equilibrium yield of methanol but has no effect on the value of the equilibrium constant KpK_{\text{p}}Kp?
Add a catalyst
Decrease the temperature
Increase the partial pressure of hydrogen
Decrease the total pressure of the system
