If activation energy is low, it is _____________ for a reaction to start.

• easy

• difficult

• neither

The ____________ states that atoms, ions, or molecules must collide in order to react.

• transition state

• activation energy

• rate law

• collision theory

The main reason an increase in temperature results in an increase of the reaction rate is that

• the potential energy of the particles increases

• the duration of the collisions between particles increases

• the force of attraction between particles increases

• the number of particles with the required activation energy increases
