2C2H2 + 5O2 -> 4CO2 + 2H2O + energy

What does the equation communicate about the relative energy of the chemical bonds in the reactants and products?

The intermolecular bonds of the reactants are weaker than that of the products' because the products' intermolecular bonds broke easily, meaning less energy was required to break the bonds of the reactants than was made when the products' bonds were formed. Thus, more energy was released.

First of all, is that right? And I think the wording can use some work, if someone could help me with making a better explanation, I'd be extremely grateful.

But thank you; haha, I wouldn't go after an American prize anyways!

The bonds of the reactants are weaker than those of the products. Less energy was required to break the bonds of the reactants than was formed for the products and energy was released in an exothermic reaction..
