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.
A catalyst speeds up a reaction and an inhibitor slows down a reaction
difference between activator and inhibitor
umm no. they are opposites. a catalyst will speed up a reaction and an inhibitor will slow it down.
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.
In chemistry it is Inhibitor
The inhibitor interferes with the catalyst in a chemical reaction.
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
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.
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.
The opposite of a catalyst is an inhibitor, something that suppresses or slows a reaction.
