AThe heat given off during any reaction
BPotential energy in bonds, released when they break
CKinetic energy carried by moving electrons
DThe free energy left after entropy is subtracted
Answer & Solution
Correct answer: B. Potential energy in bonds, released when they break
1. The fact that breaking certain chemical bonds releases energy implies that those bonds hold potential energy.
2. The type of potential energy that exists within chemical bonds and is released when those bonds break is chemical energy.
3. Chemical energy provides living cells with energy from food.
4. Free energy after entropy is accounted for is Gibbs free energy, a distinct quantity with its own definition.
