At 2 atmospheres pressure, sulfur dioxide reacts with oxygen. The forward reaction is exothermic, so heat is released. The reaction equation is given below. $2\text{SO}_2(g) + \text{O}_2(g) \rightleftharpoons 2\text{SO}_3(g)$ The mixture reaches equilibrium. The pressure is then doubled. How does the amount of sulfur trioxide produced change, and why?
- Adecreases / the forward reaction is exothermic
- Bdecreases / there are fewer molecules on the right
- Cincreases / the forward reaction is exothermic
- Dincreases / there are fewer molecules on the right
