b. By referring to Appendix C, look up the enthalpies of formation of acetylene and nitrogen. Which compound is more stable?
c. Write balanced chemical equations for the complete oxidation ofN2 to form N205(g) and of acetylene to form C02(g) and H20(g).
d. Calculate the enthalpy of oxidation per mole for N2 and for C2H2 (the enthalpy of formation of N205(g) is 11.30k.J/m01).
