Question

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

Explanation:

The total reaction energy is calculated by subtracting the total bond energy of the products from the total bond energy of the reactants. This is because breaking reactant bonds requires energy (endothermic) and forming product bonds releases energy (exothermic).

Answer:

reactant bond energy - product bond energy
