Answer:
Chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates do not.
Explanation:
In chemistry, and more specifically in the area of chemical kinetics, the reaction rate refers to a measure of how quickly a reaction takes place.
The reaction rate may determine the time a product is formed as the reagent is consumed proportionally to the concentration of product formed. This depends on the conditions that are influencing the reaction, so it is important to say that chemical reaction rates vary with reaction conditions.
Radioactive decay occurs when the nucleus of the atom of some chemical element is unstable and then it "breaks", releasing electromagnetic radiation and disintegrating. Important information about nuclear decay is that the rates of this reaction are constant and do not depend on the reaction conditions.
