The reaction equation for making sulfur trioxide from sulfur dioxide is shown below. $2\text{SO}_2(g) + \text{O}_2(g) \rightleftharpoons 2\text{SO}_3(g)$ The forward reaction releases heat. Which pairing of pressure and temperature gives the greatest equilibrium yield of sulfur trioxide?
- Ahigh pressure, high temperature
- Bhigh pressure, low temperature
- Clow pressure, high temperature
- Dlow pressure, low temperature
