Problem: Consider the following reaction:A2 + B2 → 2AB   ΔE = -285 kJThe bond energy for A2 is one-half the amount of the AB bond energy. The bond energy of B  2 = 432 kJ/mol. What is the bond energy of A2?

FREE Expert Solution

ΔE or ΔH can be calculated as:

H = bond energyreactants - bond energyproducts H = (BE A2+BE B2) -2(BE AB)

If A2 is half the amount of AB, we can set up the equation as:
