The enthalpyof reaction for the reaction :
\( \mathrm{P} \)
\[
2 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{H}_{2} \mathrm{O}(l) \text { is } 4 \mathrm{H}^{\square}=-572 \mathrm{~kJ} \mathrm{~mol}^{-1} \text {. }
\]
W
What will be standard enthalpy of formation of \( \mathrm{H}_{2} \mathrm{O}(l) \) ?
