Question 28
H

Methanol is made industrially from carbon monoxide and hydrogen. The forward reaction is exothermic.

CO(g)+2H2(g)⇌CH3OH(g) \mathrm{CO(g) + 2H_{2}(g) \rightleftharpoons CH_{3}OH(g)} CO(g)+2H2​(g)⇌CH3​OH(g)

Which change would increase both the rate of reaction and the equilibrium yield of methanol?

[1]
A

Adding a catalyst

B

Decreasing the temperature

C

Increasing the pressure

D

Increasing the temperature
