Rate of reaction — practice question

Which equation represents a reaction that takes place at room temperature and pressure?

  • A$\text{Br}_2(\text{aq}) + 2\text{NaCl}(\text{aq}) \rightarrow 2\text{NaBr}(\text{aq}) + \text{Cl}_2(\text{aq})$
  • B$\text{Br}_2(\text{aq}) + 2\text{NaI}(\text{aq}) \rightarrow 2\text{NaBr}(\text{aq}) + \text{I}_2(\text{aq})$
  • C$\text{I}_2(\text{aq}) + 2\text{NaCl}(\text{aq}) \rightarrow 2\text{NaI}(\text{aq}) + \text{Cl}_2(\text{aq})$
  • D$\text{I}_2(\text{aq}) + 2\text{NaBr}(\text{aq}) \rightarrow 2\text{NaI}(\text{aq}) + \text{Br}_2(\text{aq})$
