Collision Theory Review Game

Collision theory states that ______________.

• All collisions lead to chemical reaction .

• Most collisions lead to chemical reactions.

• Very few reactions involve particle collisions.

• Effective collisions lead to chemical reactions

When a lit match is touched to the wick of a candle, the candle begins to burn.

• Behaves as a catalyst

• Supplies activation energy

• Is part of the rate-determining step

• Lowers the activation energy barrier

For collisions to be successful, reactants must have _________.

• Favorable geometry only

• Sufficient heat of reaction only

• Sufficient potential energy only

• Sufficient kinetic energy and favorable geometry

Complete the statement: Collision theory explains rate of chemical reaction by ___________________________.

• the amount of reactant available

• the frequency of particle collisions

• measuring gas volumes

• the type of reactants

What is rate of chemical reaction?

• How much energy is needed for a reaction to occur

• The time it takes for a reaction to occur

• The energy required to break a bond

• How particles collide with each other

Which of the following are the factors that affect the rate of chemical reaction? (Check the boxes that apply.)

• Surface Area and Particle Size (Solid Reactants)

• Nature of Reactants

• Temperature

• State of Matter

• Concentration of Solutions

Which is CORRECT about temperature as one of the factors affecting rate of chemical reaction?

• The higher the temperature is, the slower will be the rate of reaction.

• The higher the temperature is, the faster will be the rate of reaction.

• The lower the temperature is, the faster will be the rate of reaction.

• The lower the temperature is, the slower will be the rate of reaction.
