Calculate the bond energy of C-H Bond in methane.

From the following bond energies : {:(H-H "bond energy :" 431.37 kJ mol^(-1)),(C=C "bond energy :" 606.10 kJ mol^(-1)),(C-C "bond energy : "336.49 kJmol^(-1)),(C-H "bond energy :" 410.50kJ mol^(-1)):} calculate the bond energy of the following reaction : H-overset(overset(H)(|))( C)= overset(overset(H)(|))(C )-H + H - H rarr H - underset(underset(H)(|))overset(overset(H)(|))(C )- underset(underset(H)(|))overset(overset(H)(|))(C)- H

Given that Bond energy of H_(2) and N_(2) are 400KJmol^(-1) and 240KJmol^(-1) respectively and DeltaH_(f) of NH_(3) is -120KJmol^(-1) calculate the bond energy of N-H bond :-

Given that Bond energy of H_(2) and N_(2) are 400KJmol^(-1) and 240KJmol^(-1) respectively and DeltaH_(f) of NH_(3) is -120KJmol^(-1) calculate the bond energy of N-H bond :-

Which of the following is the correct order for bond energy for C-H bonds in these compounds?
