Methanol is made by allowing carbon monoxide and hydrogen to react in the presence of an aluminium oxide catalyst. The reaction equation is $\text{CO(g)} + 2\text{H}_2\text{(g)} \rightleftharpoons \text{CH}_3\text{OH(g)}$. This reaction is reversible, and the forward reaction is exothermic. Which alteration to the conditions would increase the yield of methanol?
- Adecreasing the concentration of the carbon monoxide
- Bincreasing the pressure
- Cincreasing the rate of the reaction
- Dincreasing the temperature
