Why does a higher concentration increase the rate of reaction?

• it increases the amount of reactants

• it lowers the activation energy

• it increases the energy of reactant particles

• it increases the frequency of collision

Grinding an effervescent tablet into powder increases the rate of reaction due to increase of

• concentration

• total surface area

• temperature

• size

Increasing pressure causes the reacting particles

• to bond together

• to repel from each other

• gain more kinetic energy

• to move closer together

As the frequency of ________________ collision increases, the rate of reaction increases.

• time

• speed

• effective

• efficient
