(a) Given ΔH° for the reaction

along with the information that the heat of combustion of ethane is 1560 kJ/mol and that of ethylene is 1410 kJ/mol, calculate ΔH° for the hydrogenation of ethylene:

(b)  If the heat of combustion of acetylene is 1300 kJ/mol. what is the value of ΔH° for its hydrogenation to ethylene? To ethane?

(c)  What is the value of ΔH° for the hypothetical reaction
