Question 49

Ethanol vapour is formed in a reversible reaction between ethene and steam.

C2H4(g)+H2O(g)⇌C2H5OH(g) \text{C}_2\text{H}_4\text{(g)} + \text{H}_2\text{O(g)} \rightleftharpoons \text{C}_2\text{H}_5\text{OH(g)} C2​H4​(g)+H2​O(g)⇌C2​H5​OH(g)

There are two gas molecules on the left of the equation and one gas molecule on the right.

Explain how increasing the pressure affects the equilibrium yield of ethanol.
