Methanol is produced by the reaction of carbon dioxide with hydrogen. $\text{CO}_2(g) + 3\text{H}_2(g) \rightleftharpoons \text{CH}_3\text{OH}(g) + \text{H}_2\text{O}(g) \qquad \Delta H = -49\,\text{kJ mol}^{-1}$ What change increases the equilibrium yield of methanol for this process?
- Aincreasing the pressure
- Badding an excess of steam
- Cadding a catalyst
- Dincreasing the temperature
