Answer #1

$\Delta$ Hrxn = bond energies of reactants - bond energies of products

= 3(C=C)+4(C-C) +6(C-H)+(C=O) +5(N-H) +(N-N) +(C=O) +2(C-N)

-[3(C=C) +6(C-H) +4(C-C) +(C=N) + (C=O)+3(N-H)+(N-N)+2(O-H) ]

= 3*614 + 4*347+6*413 + 745 + 5*391 + 160+745 +305-(3*614+6*413+4*347+615+745+3*391+160+2*467)

= 283KJ/mole >>>answer
