Collision Theory Quiz

What are the factors that can affect the reaction rate according to collision theory?

• Shape, weight, viscosity, and pH

• Mass, density, velocity, and distance

• Temperature, concentration, surface area, and catalyst

• Color, pressure, volume, and time

Explain how temperature and concentration can affect the reaction rate based on collision theory.

• Temperature and concentration have no effect on reaction rate

• Increasing temperature decreases the frequency of collisions

• Temperature and concentration affect the reaction rate by increasing the frequency and energy of collisions, as per collision theory.

• Decreasing concentration increases the energy of collisions

What is activation energy in the context of collision theory?

• The energy needed to stop a reaction

• The energy released during a reaction

• The maximum energy required for a reaction to occur

• Minimum energy required for a reaction to occur

How does the activation energy affect the rate of a chemical reaction?

• It decreases the temperature of the reaction

• It affects the rate by determining the likelihood of successful collisions between reactant molecules.

• It increases the concentration of the reactants

• It has no effect on the rate of the reaction

What are effective collisions in the context of collision theory?

• Collisions between solid particles that do not result in a chemical reaction

• Collisions between reactant molecules that result in a chemical reaction

• Collisions between inert molecules that do not result in a chemical reaction

• Collisions between products that result in a chemical reaction

Explain the concept of effective collisions and its significance in determining reaction rate.

• Effective collisions are the collisions between reactant molecules that result in a chemical reaction.

• Effective collisions are the collisions between product molecules.

• Effective collisions are the collisions that do not result in a chemical reaction.

• Effective collisions are the collisions that occur at a very slow rate.

What is collision frequency and how does it relate to reaction rate?

• The collision frequency is the number of car accidents per year, and it relates to reaction rate by causing delays in transportation.

• The collision frequency is the frequency of arguments between people, and it relates to reaction rate by causing emotional reactions.

• The collision frequency is the rate at which particles collide in a gas, and it relates to reaction rate by increasing the temperature of the system.

• The collision frequency is the number of collisions that occur per unit time, and it relates to reaction rate by influencing the likelihood of successful reactions.

Describe the relationship between collision frequency and reaction rate.

• Directly proportional

• Fluctuates randomly

• No relationship

• Indirectly proportional

How does the orientation of collisions impact the rate of a chemical reaction?

• It has no impact on the rate of the reaction

• It causes the reaction to stop completely

• It only impacts the color of the reactants

• It affects the likelihood of successful collisions between reactant molecules.

Explain the role of collision orientation in determining the success of a reaction.

• The color of the colliding molecules determines the success of the reaction.

• The temperature of the environment determines the success of the reaction.

• The speed of the colliding molecules has no effect on the success of the reaction.

• The orientation of colliding molecules determines whether the reaction will be successful or not.
