calculate the bond enthalpy for the reaction when carbon react with hydrogen to form methane given the following enthalpies values
a)
Change heat of formation CH4 = -75kjmole -1
Change in heat of atomization H2 = 218kjmole -1
Change in heat of carbon graphite = 715kjmole -1
C graphite + 4H = Hf + 4E[C-H]
How many C-H bonds are broken in this reaction
b)
Calculate the energy for the bond breakage between C-H
