If enthalpy of dissociation of `CH_(4)` and `C_(2)H_(6)` are `320` and `360` calories respectively then bond energy of `C-C` bond is:

If the dissociation energies of 'CH_4' and 'C_2 H_6' are 360 and '620 kcal/ mol' respectively, then the bond energy of 'C -C' bond is

The dissociation energy of CH_(4) and C_(2)H_(6) are respectively 360 and 620 kcal//mol. The bond energy of C-C bond is :

The dissociation energy of CH_(4) and C_(2)H_(6) are respectively 1508 and 2594 kJ mol^(-1) respectively. The bond energy of C-C bond is

The dissociation energy of CH_4 and C_2H_6 are respectively 360and 620 kcal/mole. The bond energy of C-C bond is:

Bond dissociation energy of CH_(4) si 360 kJ/mol and C_(2)H_(6) has 620 kJ mol. Then bond dissociation energy of C-C bond is :-

Hess's law of heat of summatiion is based on law of conservation of energy. It has found significance in deriving heats of many reactions which either do not take place or if take place, than other side reactions also accompany it. For example heat of reaction for C+(1)/(2)O_(2) rarr CO can not be studied directly as it occurs with simultaneous reaction of oxidation of CO to CO_(2) . Bond energy is referred as heat enthalpy when a bond is broken to produce isolated gaseous atoms. In case of breaking up of bonds between unlike atoms e.g., C-H bond in CH_(4) , bond energy is referred as avarage bond energy as four C-H bonds are broken up. Heat of dissociation of CH_(4) and C_(2)H_(6) are 360 and 620kcal mol^(-1) . The C-C bond energy would be :
