The given reaction is Y2 + 2 X2 ---------> 2YX2
Y=Y 2 X-X 2 X-Y-X
The change in enthalpy, 
H of the reaction is given
Hrxn
= Bond dissociation energy of reactants - bond dissociation energy
of products
= Bond dissociation energy of Y=Y + 2* Bond dissociation energy of (X-X) - 4*Bond dissociation energy of (x-y)
= 449 + 2*272 - 4*174 = 297 KJ/ mole
The change in enthalpy,
H of the reaction is 297 KJ/mole
