This is called reaction rate.
Decay rate is a chemical property, as it relates to the rate at which a substance undergoes chemical reactions or transformations over time.
catalyst
The substance that slows down a chemical reaction is an inhibitor. Instead you could also call an inhibitor an anticatalyst.-anticatalyst `antee'katlist1. (chemistry) a substance that retards a chemical reaction or diminishes the activity of a catalyst
Actually a substrate is a reactant. It undergoes a chemical reaction to yield a product. The difference is that a catalyst acts upon it to increment the rate of the reaction (by reducing the activation energy required).
The Reaction Rate
Decay rate is a chemical property, as it relates to the rate at which a substance undergoes chemical reactions or transformations over time.
The average rate of disappearance for a substance in a chemical reaction is the speed at which the substance is used up over time. It is calculated by dividing the change in concentration of the substance by the change in time.
A catalyst.
The process is spelled catalysis (change in reaction rate).The substance that makes a chemical reaction change is a catalyst.
Catalyst is a a substance that raises the rate of a chemical reaction without necessarily experiencing any any permanent chemical change.
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. a person or thing that precipitates an event.
A catalyst doesn't undergo a chemical change during a chemical reaction.
The rate of disappearance formula is used to calculate the speed at which a substance is consumed or transformed in a chemical reaction. It is typically expressed as the change in concentration of the reactant over time.

This is a very vague question and would depend on the chemical that you are talking about. The easiest way I can think to explain it on a wide variety of chemicals is by using a catalyst (speeds up the process of a chemical reaction), or the use of an antagonist (Slows a chemical reaction). I hope this helps, but without any specific chemicals being named this is the best i can do. :) By heating we can change the rate of chemical change(reaction).
