Explain Bond Energy Changes Practice Test

The reaction is exothermic because bond breaking does not require any energy input.

The reaction is exothermic because forming C=O and O–H bonds releases more energy than is required to break C–H and O=O bonds.

The reaction is exothermic because stronger bonds are easier to break, so less energy is needed to start the reaction.

The reaction is exothermic because breaking C–H and O=O bonds releases more energy than is released when new bonds form.
