At $25\ ^\circ\text{C}$, bromine undergoes reaction with aqueous sodium hydroxide. Reaction 1: $\text{Br}_2(aq) + 2\text{NaOH}(aq) \rightarrow \text{NaBr}(aq) + \text{NaOBr}(aq) + \text{H}_2\text{O}(l)$. The $\text{NaOBr}$ produced is unstable at $25\ ^\circ\text{C}$ and reacts further. Reaction 2: $3\text{NaOBr}(aq) \rightarrow 2\text{NaBr}(aq) + \text{NaBrO}_3(aq)$. Which reactions are disproportionation reactions?
- Aboth reaction 1 and reaction 2
- Bneither reaction 1 nor reaction 2
- Creaction 1 only
- Dreaction 2 only
