Estimate ΔrH° for forming 2 mol ammonia from molecular nitrogen and molecular hydrogen. Is this reaction exothermic or endothermic?

The bond energy of a C—C single bond averages 347 kJ mol-1; that of a CC triple bond averages 839 kJ mol-1. Explain why the triple bond is not three times as strong as a single bond.

Explain how the dipole moment could be used to distinguish between the cis and trans isomers of 1,2-dibromoethene:
