Question

how is total reaction energy calculated? (1 point) product bond energy + reactant bond energy reactant bond energy + product bond energy reactant bond energy - product bond energy product bond energy × reactant bond energy

Explanation:

The total reaction energy is calculated by subtracting the product - bond energy from the reactant - bond energy. This is because breaking reactant bonds requires energy input and forming product bonds releases energy.

Answer:

C. reactant bond energy - product bond energy
