This is called reaction rate.
It is a catalyst.
A catalyst is a substance that accelerates or increases the rate of a chemical reaction. In principle a catalyst should remain unaffected during the process. However normally it loses some activity during it resuses.
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 substance that speeds up a chemical reaction is known as a CATALYST.
They are called catalysts.
