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

• transition state

• activation energy

• rate law

• collision theory

The minimum amount of energy needed for colliding particles to react is called the

• Chemical Energy

• Kinetic Energy

• Activation Energy

• Potential Energy

How does a catalyst work in speeding up a reaction?

• By lowering the activation energy or reaction

• by giving them more energy

• by making them more available
