Question 1

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)⇌CH3​OH(g)

Which change increases the equilibrium yield of methanol but has no effect on the value of the equilibrium constant KpK_{\text{p}}Kp​?

A

Add a catalyst

B

Decrease the temperature

C

Increase the partial pressure of hydrogen

D

Decrease the total pressure of the system
