For the reaction: H2(g)+C2H4(g)-->C2H6(g)
Bond & Bond Enthalpy
H-H 436.4 kJ/mole
C-H 414 kJ/mol
C-C 347 kJ/mol
C=C 620 kJ/mol
Substance & delta Hf
H2 0
C2H4 52.3
C2H6 -84.7
(a) estimate the enthalpy of reaction, using the bond enthalpy values from the table in kJ/mol
(b) Calculate the enthalpy of reaction, using standard enthalpies of formation
