The correct answer is "exothermic".
The correct answer is "exothermic." To understand why, let's break down the options and their meanings:
1. Catalyst: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It does not directly relate to the release of energy in a reaction.
2. Exothermic: An exothermic reaction is a chemical reaction that releases heat or energy to the surroundings. In other words, it gives off more energy than it uses, which matches the description given in the question.
3. Emeritus: Emeritus refers to a retired or former position, typically used in academic or professional contexts. It does not relate to chemical reactions or energy release.
4. Lactic: Lactic acid is a organic acid that can be formed in the body during certain metabolic processes, but it does not directly relate to the energy release in chemical reactions.
Therefore, the correct answer is "exothermic" because it accurately describes a reaction that releases more energy than it uses.
