A surplus of chlorine gas, $\text{Cl}_2$, is bubbled through $60\,\text{cm}^3$ of cold aqueous $0.1\,\text{mol dm}^{-3}$ sodium hydroxide. In another experiment, chlorine gas in excess is bubbled through $60\,\text{cm}^3$ of hot aqueous $0.1\,\text{mol dm}^{-3}$ sodium hydroxide until the reaction no longer continues. What extra amount of sodium chloride is formed in the reaction with hot $\text{NaOH}$ compared with cold $\text{NaOH}$?
- A$0.002\,\text{mol}$
- B$0.003\,\text{mol}$
- C$0.005\,\text{mol}$
- D$0.006\,\text{mol}$
