The production of methanol from carbon monoxide and hydrogen is represented by the following reversible reaction:
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)⇌CH3OH(g)At a certain temperature, an equilibrium mixture contains 0.45 mol of CO\text{CO}CO, 1.20 mol of H2\text{H}_2H2, and 0.75 mol of CH3OH\text{CH}_3\text{OH}CH3OH. The total pressure of the system is 16.0 MPa.
