A proportion of crude oils contain $\text{H}_2\text{S}$. In refining, the Claus process turns the $\text{H}_2\text{S}$ into solid sulfur, and this is then taken off. reaction I $2\text{H}_2\text{S}(g) + 3\text{O}_2(g) \rightarrow 2\text{H}_2\text{O}(l) + 2\text{SO}_2(g)$ reaction II $2\text{H}_2\text{S}(g) + \text{SO}_2(g) \rightarrow 2\text{H}_2\text{O}(l) + 3\text{S}(s)$ Which of the statements about the Claus process are correct?
- A1, 2 and 3 are correct
- B1 and 2 only are correct
- C2 and 3 only are correct
- D1 only is correct
