What is a A substance that speeds up a chemical reaction without being permanently changed itself?

Answer 1

This is a catalyst. A catalyst doesn't get destroyed during the reaction. Rather it's more of a reaction site where two substances can combine. One example of a catalyst is amyl alcohol, which can be used to produce pure potassium metal. However, it's destroyed during the process if there are impurities in the reaction because it's consumed in other reactions. Other examples of catalysts include catalase, platinum, and manganese(IV) oxide.

Answer 2

that substance is called a catalyst. Sometimes a catalyst can also decrease the speed..then it is specifically called negative catalyst....but if it speeds up the reaction it is called positive catalyst...but you could simply say "catalyst"

Answer 3

A catalyst. Though the chemical will undergo a change or changes during the reaction, it will finish the reaction as it started.

Answer 4

A substance that increases the rate of chemical reaction without suffering any permanent chemical change is a catalyst.

Answer 5

These substances are the catalysts.

Answer 6

That's a catalyst.

Answer 7

catalyst

Answer 8

An Enzyme
