1. The following (unbalanced) combustion reaction occurs in an oxyacetylene torch:
H-C=C-H+
AH (C₂H₂, g) = 227.4 kJ/mol
AH (O2. g) = ???
AH (CO2, g) = -393.5 kJ/mol
AH (H₂O, g) = -241.8 kJ/mol
ΔΟΞΟ
Balance the reaction (fill in the boxes), then calculate the bond dissociation energy (in kJ/mol) of
the O-O bond (Do-o). Hint: consider two different methods for determining AH-
