Answer:
d. adding an inhibitor
c. fish that emit light
c. released
Explanation:
An inhibitor is a negative catalyst. It is usually a substance that slows down the rate of chemical reaction.
Chemical inhibitors acts in way that makes reactions drags over time.
Increasing temperature, increasing concentration and decreasing particle size all will increase the rate of chemical reaction. They make reactions proceed more faster.
When a fish emits light, it is not an exothermic reaction.
An exothermic reaction is one in which heat is released to the environment. In such reactions, heat is liberated to the surroundings. At the end of the reaction, the surrounding will have a higher temperature compared to the reaction.
We assign exothermic reactions a negative value because the sum of heat contents of products is less than that of reactants.
