Question 4

Methanol can be produced by the reaction of carbon monoxide with hydrogen.

Carbon monoxide reacts with hydrogen in the presence of a copper-based catalyst to produce methanol, and a dynamic equilibrium is reached.

The equation for this equilibrium reaction is:

CO(g)+2H2(g)⇌CH3OH(g) \text{CO}(\text{g}) + 2\text{H}_2(\text{g}) \rightleftharpoons \text{CH}_3\text{OH}(\text{g}) CO(g)+2H2​(g)⇌CH3​OH(g)

The forward reaction releases heat energy and is exothermic.

Describe the effect of the catalyst on the rate of attainment of equilibrium and on the equilibrium yield of products.
