Read each question carefully and answer to the best of your ability. Show all your work for calculations.

1. What does Collision Theory state is necessary for a chemical reaction to occur?

a

Reactants must be in the same phase.

b

Reactant particles must collide with sufficient energy and correct orientation.

c

A catalyst must be present.

d

The reaction vessel must be sealed.

2. What is activation energy?

a

The energy released during a reaction.

b

The minimum energy required for a reaction to occur.

c

The energy of the products.

d

The energy of the reactants.

3. According to Collision Theory, increasing the temperature of a reaction will generally   the reaction rate because it increases the frequency and energy of collisions.

4. For a collision to be effective, particles must collide with sufficient energy and the correct  .

5. All collisions between reactant particles lead to a chemical reaction.

T

True

F

False

6. A catalyst works by increasing the activation energy of a reaction.

T

True

F

False

7. Explain how increasing the surface area of a solid reactant affects the rate of reaction based on Collision Theory.

8. Describe the two main requirements for an effective collision between reactant particles.
