The equations for the reactions in the process are given. reaction 1: $\text{2SO}_2(g) + \text{O}_2(g) \rightleftharpoons \text{2SO}_3(g) \quad \Delta H = -198\,\text{kJ mol}^{-1}$ reaction 2: $\text{SO}_3(g) + \text{H}_2\text{O}(l) \rightarrow \text{H}_2\text{SO}_4(aq)$ Which of the statements below are true?
- A1 and 2 only
- B1 and 3 only
- C2 and 3 only
