Question

What's catalyst. The properties of catalyst

Answer 1

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.

Answer 2

Step-by-step explanation:

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.

properties:

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