AP Chemistry Unit 5 Kinetics

Question 1

Why does an increase in temperature increase the rate of a reaction?

shift the equilibrium to favor the products C There are more collisions per second that will have the proper energy to exceed the activation energy. reverse E a < forward Ea and ΔH is endothermic

Correct Answer:

There are more collisions per second that will have the proper energy to exceed the activation energy.

Explanation:

Correct answer: There are more collisions per second that will have the proper energy to exceed the activation energy.

Question 2

A change in temperature of 10 degrees was found to triple the rate of a particular chemical reaction. How does this change in temperature affect the reacting molecules?

The intermediate molecules contain normal bonds rather than partial bonds and can be occasionally isolated. activation energy, orientation, and frequency The number of molecules above the reaction energy threshold triple. shift the equilibrium to favor the products

Correct Answer:

The number of molecules above the reaction energy threshold triple.

Explanation:

Correct answer: The number of molecules above the reaction energy threshold triple.

Question 3

In a series of chemical reactions, how do the reaction intermediates differ from the activated complexes?

(A) There are more collisions per second that will have the proper energy to exceed the activation energy. The intermediate molecules contain normal bonds rather than partial bonds and can be occasionally isolated. reverse E a < forward Ea and ΔH is endothermic

Correct Answer:

The intermediate molecules contain normal bonds rather than partial bonds and can be occasionally isolated.

Explanation:

Correct answer: The intermediate molecules contain normal bonds rather than partial bonds and can be occasionally isolated.

Question 4

The rate of a chemical reaction is related to

There are more collisions per second that will have the proper energy to exceed the activation energy. Halving the concentration of A and quadrupling the concentration of B activation energy, orientation, and frequency The intermediate molecules contain normal bonds rather than partial bonds and can be occasionally isolated.

Correct Answer:

activation energy, orientation, and frequency

Explanation:

Correct answer: activation energy, orientation, and frequency

Question 5

Questions 5 and 6 refer to the following proposed mechanism for the reaction of chlorine gas with chloroform, CHCl 3 , to form carbon 5. What is the overall reaction equation for this mechanism?

Rate = 0.45 hr -1 [ 12 H 22 O 11 ] Cl 2 (g) + CHCl 3 (g) → HCl(g) + CCl 4 (g) 15 M –2 min –1 4

Correct Answer:

Cl 2 (g) + CHCl 3 (g) → HCl(g) + CCl 4 (g)

Explanation:

Correct answer: Cl 2 (g) + CHCl 3 (g) → HCl(g) + CCl 4 (g)
