Question 1

Given the bond enthalpies CC (348), CO (707), OO (498), HO (464), CH (414) all in kJ/mol, compute ΔH° in kJ/mol for the complete combustion of C7H16.
◦ -3.13 × 103 kJ/mol
◦ -2.93 × 103 kJ/mol
◦ -2.57 × 103 kJ/mol
◦ -2.43 × 103 kJ/mol
◦ +2.57 × 103 kJ/mol

Question 2

Given the bond enthalpies CC (611), CC (837), HH (436),CH (414) all in kJ/mol, estimate ΔH° for the following reaction: C2H2(g) + H2(g) → C2H4(g).
◦ -60 kJ/mol
◦ -166 kJ/mol
◦ -994 kJ/mol
◦ +166 kJ/mol
