The enthalpy change for the following reaction, \( \mathrm{NaOH}(a q)+.\mathrm{HCl}(a q.) \rightarrow \mathrm{NaCl}(a q)+.\mathrm{H}_{2} \mathrm{O}(l) \) is \( -57 \mathrm{~kJ} \). Predict the value of the enthalpy change in the following reaction:
\[
\mathrm{Ba}(\mathrm{OH})_{2}+\mathrm{H}_{2} \mathrm{SO}_{4}(a q .) \longrightarrow \mathrm{BaSO}_{4}(s)+2 \mathrm{H}_{2} \mathrm{O}(l)
\]
(A) \( -57 \mathrm{~kJ} \)
(B) \( -114 \mathrm{~kJ} \)
(C) \( -76 \mathrm{~kJ} \)
(D) \( -228 \mathrm{~kJ} \)
