For reaction 1, the enthalpy change is $-114\,\text{kJ mol}^{-1}$. $2\text{NaOH}(aq) + \text{H}_2\text{SO}_4(aq) \rightarrow \text{Na}_2\text{SO}_4(aq) + 2\text{H}_2\text{O}(l)$ (reaction 1) Using this data, what is the best estimate for the enthalpy change of reaction 2? $\text{Ba(OH)}_2(aq) + 2\text{HCl}(aq) \rightarrow \text{BaCl}_2(aq) + 2\text{H}_2\text{O}(l)$ (reaction 2)
- A$-57\,\text{kJ mol}^{-1}$
- B$-76\,\text{kJ mol}^{-1}$
- C$-114\,\text{kJ mol}^{-1}$
- D$-228\,\text{kJ mol}^{-1}$
