Question
Using the provided bond energies, estimate the AHrxn for the
generic reaction below. The skeletal structures of each
molecule are shown below the balanced equation, where each
(-) represents a single bond.
2 A2 B → 2 A2 + B2
2 (A – B – A)
→ 2 (A – A) + (B – B)

-
Bond energies: (A-B) = 150. kJ/mol; (A-A) = 200. kJ/mol; (B-B)
%3D
= 250. kJ/mol
O -300. kJ
O 350. kJ
O -50. kJ
600. kJ
O 1250. kJ
