Question 14

A mixture of 1.00 mol of CO(g)\text{CO}(\text{g})CO(g) and 3.00 mol of H2(g)\text{H}_2(\text{g})H2​(g) is allowed to reach equilibrium in a sealed vessel at a constant temperature.

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)

At equilibrium, the mixture contains 0.50 mol of CH3OH(g)\text{CH}_3\text{OH}(\text{g})CH3​OH(g). The total pressure of the equilibrium mixture is 450 kPa.

What is the partial pressure of H2(g)\text{H}_2(\text{g})H2​(g) at equilibrium?
