Using average bond energy values estimate ΔH for the following gas phase reaction.?

Question

4CH2=CHCH3 + 6NO → 4CH2=CHCN + 6H2O + N2

Answer 1

You're going to have to do that yourself. A bond that breaks will have a positive enthalpy change, while each bond that forms will have a negative value.

Draw out the structures of the compounds in the reaction, determine which bonds are broken and which are formed, and then add up all the enthalpy values.
