Trevor Dominguez · Answer 1

Because the particles are smaller, a reactant would be exposed to more cobalt atoms. This would cause the reaction to happen quicker than with larger particles.

Johnny Doyle · Answer 2

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.
