A catalyst speeds up a reaction and an inhibitor slows down a reaction
Catalyst: a substance which promote and help a chemical reaction. Inhibitor: a substance which greatly reduces the rate of a chemical reaction.
A catalyst lower the activation energy (speeds up the reaction) while an inhibitor increases the activation energy (slows it down).
Catalyst speeds up reactions, and inhibitors are used to slow down reactions.
The opposite of a catalyst is an inhibitor, something that suppresses or slows a reaction.
In chemistry it is Inhibitor
A negative catalyst is added to a reaction to slow down a process as does an inhibitor. From this you could say that they are equivalent.
No, a catalyst and an inhibitor serve different purposes in a chemical reaction. A catalyst increases the rate of a chemical reaction by lowering the activation energy, while an inhibitor decreases the rate of a reaction by interfering with the reaction mechanism. They cannot be used interchangeably.
An "inhibitor" (aka negative catalyst) slows or blocks a chemical reaction. In some cases this can also be called a deterrent or a retardant. The term anticatalyst(anti-catalyst) refers to blocking the action of a catalyst.
Lemon juice can be used as catalyst in organic chemistry.
inhibitor
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
An inhibitor is a substance that interferes with a catalyst. Inhibitors also interfere with other biologic activity such as growth.
