Change in enthalpy for reaction,
P \( 2 \mathrm{H}_{2} \mathrm{O}_{2(l)} \rightarrow 2 \mathrm{H}_{2} \mathrm{O}_{(l)}+\mathrm{O}_{2(g)} \)
if heat of formation of \( \mathrm{H}_{2} \mathrm{O}_{2(l)} \) and \( \mathrm{H}_{2} \mathrm{O}_{(l)} \) are \( -188 \)
W and \( -286 \mathrm{~kJ} / \mathrm{mol} \) respectively, is
(a) \( -196 \mathrm{~kJ} / \mathrm{mol} \)
(b) \( +196 \mathrm{~kJ} / \mathrm{mol} \)
(c) \( +948 \mathrm{~kJ} / \mathrm{mol} \)
(d) \( -948 \mathrm{~kJ} / \mathrm{mole} \)
\( (2001) \)
