Bond Energy Of Nh3
Calculate the average binding energy of NH in NH3 (g). 3
Calculate the average binding energy of NH in NH3 (g). NH3 (g) = 46.11 for kJ / mol, N (g) = 472.7 kJ / mol, H (g) = 218.0 kJ / mol, N2 (g) = 0 for kJ / mol, H2 ( g) = for 0 kJ / mol.
Can you fix this for me? I'm not sure what they're asking for. Any help is greatly appreciated.
the answer
1. The process of breaking endothermic bonds
NH3 per 1 til
472.7 kj is required to break N2 (g) 1/ into 1/2 mol N. power
3/2 mole H2 (g) requires 3 * 218 kj to dissolve in 3H. power
Total absorbed energy = + 1120.7 kj
2. Exothermic bond formation process
The formation of NH3 consisting of 3 NH bonds releases 1 til 46.11 kJ. power
Bond net energy 3 NH or 1 mole of NH3 = [broken bond] = + 1120.7 (46.11) = 1166.81 kj
Binding is an average binding energy for NH = 1166.81 / 3 = 389 kj
