What is a promoter in chemical reactions?

A promoter is indeed a type of catalyst that speeds up a chemical reaction. Catalysts are substances that increase the rate of chemical reactions without being consumed in the process. By providing an alternative pathway for the reaction with a lower activation energy, promoters facilitate more efficient interactions between reactants, resulting in an increased reaction rate.

This role is crucial in various industrial processes where enhancing the speed of reaction can lead to better efficiency and productivity. While some substances can inhibit reactions or have no effect at all, the essence of a promoter lies in its ability to accelerate the reaction, contributing positively to the overall yield of the desired product.
