Question

give an equation to explain the meaning of catalyst inhabiter and promoter​

Answer 1

Answer:

In the field of chemical kinetics, promoters can be defined as substances that work to increase the catalytic activity of a given catalyst. It can be noted that promoters are not catalysts by themselves. On the other hand, inhibitors (commonly known as “negative catalysts”) work to decrease the reaction rate by lowering the activity of the catalyst. Inhibitors may even modify the selectivity of the catalyst along with the rate of the reaction.

Hope this helps

Answer 2

Promoters are substances that increase the catalytic activity, even though they are not catalysts by themselves. Inhibitors are sometimes referred to as "negative catalysts" since they decrease the reaction rate.

Such substances are referred to as catalysts if they accelerate reaction, and inhibitors if they slow it down. 75 % of processes used in chemical industry are catalytic. Examples are: ammonia synthesis and oxidation, sulfuric acid production, and fine organic synthesis, for example, medicines

A substance which increases the catalyst activity is known as catalyst promoter. Example: In harber's cycle molybdenum or mixture of potassium and aluminium oxides act as promoters. Lindler's catalyst used in the hydrogenation of alkyne to an alkene acts as a catalyst poison.
