Reversible reactions and equilibrium — practice question

Methanol is produced when carbon monoxide reacts with hydrogen. This reaction is exothermic and reaches chemical equilibrium. The reaction equation is $\text{CO}(g) + 2\text{H}_2(g) \rightleftharpoons \text{CH}_3\text{OH}(g)$. Which changes in temperature and pressure would increase the yield of methanol?

  • Atemperature decrease, pressure decrease
  • Btemperature decrease, pressure increase
  • Ctemperature increase, pressure decrease
  • Dtemperature increase, pressure increase
