Question 8

Methanol (CH3OH\text{CH}_3\text{OH}CH3​OH) is synthesized industrially by reacting carbon monoxide with hydrogen gas:

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)

This reversible reaction is typically carried out at a pressure of 50 atm to reach a dynamic equilibrium.

Explain the effect on the rate of attainment of equilibrium if the process is carried out at a pressure higher than 50 atm.
