It's not 12 letters, but you said "reduced" so I'm reducing the letters to 7: catalyst
crank
s is for speed

As a verb, (to) rush.As a noun, pace.As an adjective, fast.
chemical reaction
to speed up a chemical reaction
Activation energy is lowered to speed up a chemical reaction.
The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.
A catalyst can speed up a chemical reaction.
Catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction (or the rate of the reaction) increases.
It will increase or decrease the speed of the chemical reaction.
Catalysts speed up the chemical reaction.
Enzymes are catalysts in a chemical reaction, they are used in chemistry to increase the speed of a specific chemical reaction. A single enzyme will not speed up multiple chemical reactions, usually it is limited to one reactant.
The catalysts can be used to increase or decrease the speed of a chemical reaction. The catalysts which reduce the speed of a reaction are called negative catalysts. They decrease the speed of the reaction by increasing the activation energy of the reaction.
Anything that is added to a chemical reaction that's intended to speed up the reaction - is a catalyst.
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
