Catalyst

Have you ever noticed how adding yeast makes bread dough rise faster? This is similar to how a catalyst works in chemistry.

A catalyst is like an assistant that is not a reactant and does not take part in the reaction. But it helps speed up the chemical reaction without being used or changing itself.

Imagine walking to school. The usual route takes a lot of time and effort.

One day, someone shows you a shortcut that gets you there faster and with less energy.

Similarly, a catalyst shows a shortcut for reactants to react easily and quickly to become the product.

It lowers the activation energy, the energy needed to start the reaction, by temporarily bonding with the reactants.

Most chemical reactions in living things need catalysts, called enzymes.

For example, amylase, an enzyme in saliva, helps break down starch in food into sugar molecules, making digestion faster and more efficient.

Catalysts play a crucial role in industry by enhancing the efficiency of chemical reactions, reducing energy consumption, and enabling sustainability.
