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
The opposite reaction of a catalyst would be an inhibitor. An inhibitor slows down or prevents a chemical reaction from occurring, whereas a catalyst speeds up the reaction.
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 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.
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.
The heterogeneous catalyst is not mixed with the reactants.
