    a catalyst is a substance that changes the rate of reaction. there are three types organic or biocatalyst (enzymes), heterogeneous catalysts and homogeneous catalyst but it remains unchanged after the reaction.


    it remains unchanged after the reaction. it is ph specific it is reaction specific it improves the product yield

    Catalyst is a substance that increases the rate of a chemical reaction but is chemically unchanged at the end of the reaction.

    properties of catalyst:

    1. A catalyst increases the speed of a reaction, and it also improves the yield of the intended product.

    2. A catalyst actually takes part in the reaction even though it itself is not consumed or used up in the course of the reaction.

    3. A catalyst makes the reaction faster by providing an alternative pathway with a lower activation energy.

    4. A catalyst is reaction-specific. It may not be effective in another reaction even if the two reactions are of similar type.

    5. In a reversible reaction, a catalyst accelerates both the forward and the reverse reactions. So, the inclusion of a catalyst does not alter the equilibrium constant of a reversible reaction.
