Equation 1 and equation 2 illustrate two separate reactions between halide ion Q$^-$ and concentrated sulfuric acid. Equation 1: $\text{H}_2\text{SO}_4 + \text{Q}^- \rightarrow \text{HSO}_4^- + \text{HQ}$. Equation 2: $\text{H}_2\text{SO}_4 + 2\text{Q}^- + 2\text{H}^+ \rightarrow \text{SO}_2 + \text{Q}_2 + 2\text{H}_2\text{O}$. Which halide ion is Q?
- A$\text{Cl}^-$ or $\text{Br}^-$
- B$\text{Br}^-$ or $\text{I}^-$
- C$\text{Cl}^-$ only
- D$\text{I}^-$ only
