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
