Mora measures the speed of the particles in a solid mass. she wants to speed up the action. which action will allow her to do so? adding more mass breaking it apart using an inhibitor lowering the activation energy

Option (b) is the correct answer.

Explanation:

One of the best way to increase the speed of particles in a solid mass is that increasing the surface area. This can be done by breaking the solid mass into various particles.

Due to this there will be increase in number of particles and as a result, it will lead to more number of collisions. Hence, there will be increase in rate of a reaction.

Thus, we can conclude that action of breaking it apart will allow Mora to increase the speed of particles.
