Question

How is total reaction energy calculated?(1 point) Responses product bond energy × reactant bond energy product bond energy × reactant bond energy reactant bond energy + product bond energy reactant bond energy + product bond energy reactant bond energy – product bond energy reactant bond energy – product bond energy product bond energy ÷ reactant bond energy

Answer 1

The total reaction energy is typically calculated using the bond energies of the reactants and products. The correct way to express this calculation is:

**Total Reaction Energy = Reactant Bond Energy – Product Bond Energy**

This represents the overall change in energy as bonds are broken in the reactants and formed in the products.

So, the correct response is:

**Reactant bond energy – Product bond energy**.
