When a reaction is described as exothermic, it means that the reaction releases energy, usually in the form of heat, as it proceeds. In the context of your options, the correct interpretation would be:

**It would occur without additional energy.**

This indicates that the reaction can proceed spontaneously once it is initiated, as the release of energy helps to sustain the process. The other options do not accurately describe an exothermic reaction.
