Question

Why is 1g of cobalt oxide nanoparticles a better catalyst than 1g of cobalt oxide powder?

Answer 1

Answer;

It is because nano particles have a large surface area compared to the powder.

Explanation;

-The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder.

-If the surface area of a reactant is increased, it means more particles are exposed to the other reactant.
