Use bond energies to estimate the enthalpy change for the following reaction

C2H2 + H2-> C2H4

i figured the bonds broken are:
1 C triple bond C 1(812kj/mol)
2 C-H 2(414kj/mol)
1 H-H 1(435kj/mol)

Bonds formed
1 C=C 1(590kj/mol)
4 C-H 4(435kj/mol)

Is this right

NVM FIGURED IT OUT

It looks ok to me.
