Detailed explanation-1: -The process of speeding up a reaction by reducing its activation energy is known as catalysis, and the factor that’s added to lower the activation energy is called a catalyst.
Detailed explanation-2: -A catalyst (KAT-l-ihst) is a substance that decreases the activation energy needed to start a chemical reac-tion. As a result, a catalyst also increases the rate of the chemical reaction, or makes the products form faster. A catalyst takes part in a chemical reaction, but it does not get changed or used up.
Detailed explanation-3: -A catalyst lowers the activation energy by changing the transition state of the reaction. The reaction then goes through a different pathway/mechanism than the uncatalyzed reaction. The catalyst does not change the net energy difference between reactant and product.
