The methanol synthesis equation is shown below. $\text{CO}_2 + 3\text{H}_2 \rightleftharpoons \text{CH}_3\text{OH} + \text{H}_2\text{O} \qquad \Delta H = -49\,\text{kJ mol}^{-1}$ Under which conditions would the highest yield of methanol be obtained at equilibrium?
- Ahigh pressure, $80\,^{\circ}\text{C}$
- Bhigh pressure, $20\,^{\circ}\text{C}$
- Clow pressure, $80\,^{\circ}\text{C}$
- Dlow pressure, $20\,^{\circ}\text{C}$
