Given the bond energies of N ≡ N , H − H and N − H bonds as 941.5, 433 and 391 kJ mole-1 respectively, the enthalpy of reaction N2(g) + 3H2g → 2NH3(g)  is
  • a)
    -93 kJ
  • b)
    102 kJ
  • c)
    90 kJ
  • d)
    -105 kJ
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Given the bond energies of N ≡ N , H − H and N − H b...
Enthalpy of reaction = ∑ bond energyreactant - ∑ bond energyproduct
= bond energy (n2) + 3 x (bond energy) (h2) - 2 x (bond energy) (NH3)
= 941.5 + (3 x 433) - 2 x 3 x 391
= 2240.5 - 2346 = 105.4 ≅ -105kJ
