Question 2

Estimate the enthalpy change for the combustion of one mole of acetylene, C2H2, to form carbon dioxide and water vapor.
         BE(C–H) = 456 kJ/mol
         BE(C≡C) = 962 kJ/mol
         BE(O=O) = 499 kJ/mol
         BE(C=O) = 802 kJ/mol
         BE(O–H) = 462 kJ/mol
◦ +1010 kJ/mol
◦ +653 kJ/mol
◦ –155 kJ/mol
