GENERAL KNOWLEDGE

Detailed explanation-1: -A catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction. Catalysis is the process of adding a catalyst to facilitate a reaction.

Detailed explanation-2: -A catalyst can lower the activation energy for a reaction by: orienting the reacting particles in such a way that successful collisions are more likely. reacting with the reactants to form an intermediate that requires lower energy to form the product.

Detailed explanation-3: -Enzyme lowers the amount of energy needed to allow the reaction to proceed. The activation energy is the specific energy level that is required for a reaction to occur. It is the minimum free energy that activates the specific reaction. The enzymes act as biological catalysts in the reactions.
