Grinding a tablet into powder increases the rate of reaction due to increased_____

• concentration

• surface area

• temperature

• catalyst

Why does a higher concentration increase the rate of reaction?

• it increases the speed of particles

• it lowers the activation energy

• it increases the energy of particle collisions

• it increases the frequency of particle collisions

A temperature increase causes the particles to ______

• slow down

• move faster

• collide less

• collide slower

Increasing the temperature gives particles more __________.

• Reaction time

• Kinetic energy

• Concentration

• Frequency

Why does a higher temperature increase the rate of a reaction?

• it increases both the frequency and energy of particle collisions

• it only increases the frequency of particle collisions

• it only increases the energy of particle collisions

• it reduces the activation energy of the reaction
