Question 2

The industrial synthesis of methanol from carbon monoxide and hydrogen is a reversible reaction:

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)

The process is typically carried out at a pressure of 50 atmospheres.

Explain the effect that a pressure higher than 50 atmospheres would have on:

a.
  • the rate of attainment of equilibrium
[2]
b.
  • the equilibrium yield of methanol
[2]
