🤓 Based on our data, we think this question is relevant for Professor Costanza's class at USF.

**2 SO _{2}_{(g)} + O_{2}_{(g)} ⇌ 2SO_{3}_{(g)}**;

**Step 1****. **Construct an ICE table.

At 1100 K, *K*_{p} = 0.25 for the reaction

2SO_{2}(g) + O_{2}(*g*) ⇌ 2SO_{3}(*g*)

Calculate the equilibrium partial pressures of SO_{2}, O_{2}, and SO_{3} produced from an initial mixture in which *P*_{SO2} = *P*_{O2} = 0.50 atm and *P*_{SO3} = 0. (Hint: If you don’t have a graphing calculator, then use the method of successive approximations to solve, as discussed in Appendix 1.4.)
