Write the reaction for breaking all the bonds in C6H6(g) use

Consider benzene (C6H6) in the gas phase. A) Write the reaction for breaking all the bonds in C6H6(g) use delta H formation data to calculate enthalpy for this reaction. B) Write the reaction that corresponds to breaking all of the carbon-carbon bonds in C6H6(g). C) By combining your answers in A and B and using average bond enthalpies for C-H calculate average bond enthalpies of the carbon-carbon bonds in C6H6(g).For a I have c6h6 g forms 6c g and 3h2 g enthalpy change is 4227.5 kj/molFor b I have c6h6 g forms 6ch gFor c given average bond enthalpy of c- h is 413 kj/ mol how do I find average bond enthalp for c-c in c6h6 g?
