Enthalpy change for the reaction,
P \( 4 \mathrm{H}_{(g)} \rightarrow 2 \mathrm{H}_{2(g)} \) is \( -869.6 \mathrm{~kJ} \)
The dissociation energy of \( \mathrm{H}-\mathrm{H} \) bond is
W
(a) \( -434.8 \mathrm{~kJ} \)
(b) \( -869.6 \mathrm{~kJ} \)
(c) \( +434.8 \mathrm{~kJ} \)
(d) \( +217.4 \mathrm{~kJ} \)
