Question

Is a catalyst consumed in reaction?

Answer 1

1. A catalyst is a substance that is added to the reaction for speeds up the chemical reaction by reducing the activation energy, without getting consumed in the chemical reaction.
2. A catalyst is not consumed in a chemical reaction. It lowers the activation energy.
3. It only provides the platform for the reaction.
4. It joins the reactants for a small time and helps them to join with each other.
5. When reactants join together the catalyst separates from them and the product is formed.
6. For example: $2{\mathrm{CH}}_3-\mathrm{Cl}+2\mathrm{Na}\stackrel{\mathrm{Dry}\mathrm{ether}}{\to }{\mathrm{CH}}_3-{\mathrm{CH}}_3+2\mathrm{NaCl}$, in this reaction, dry ether is a catalyst, and the reaction named as Wurtz reaction.

Catalyst does not consume in reaction.
