A student combines $25.0\,\text{cm}^3$ of $0.350\,\text{mol dm}^{-3}$ sodium hydroxide solution with $25.0\,\text{cm}^3$ of $0.350\,\text{mol dm}^{-3}$ hydrochloric acid. The temperature rises by $2.5\,\degree\text{C}$. No heat is transferred to the surroundings. The resulting mixture has a specific heat capacity of $4.2\,\text{J cm}^{-3}\,\text{K}^{-1}$. Determine the molar enthalpy change for the reaction?
- A$-150\,\text{kJ mol}^{-1}$
- B$-60\,\text{kJ mol}^{-1}$
- C$-30\,\text{kJ mol}^{-1}$
- D$-0.15\,\text{kJ mol}^{-1}$
