Question

What does a catalyst do in a chemical reaction?

Answer 1

Answer:

Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership.

Answer 2

Answer :

$\bigstar\bf\:Effect\:of\:catalyst:$

• A catalyst is a substance which increase the rate of a reaction without itself undergoing any permanent chemical change
• Catalyst provides an alternate pathway or reaction mechanism by reducing the activation energy between reactants and products and hence lowering the potential energy barrier.
• A catalyst does not alter Gibbs energy, ∆G and ∆H of a reaction. It catalyses the spontaneous reaction s but does not catalyse non-spontaneous reactions.
• A catalyst does not change the equilibrium constant of a reaction rather, it helps in attaining the equilibrium faster.
