AP MCQ 05ABCDEFGHIJK PART 2

  • Question 01:

    Which situation best describes a successful collision (one that leads to a chemical reaction)?

  • Question 02:

    Collision theory predicts which of the following?

  • Question 03:

    Which of the following is a bimolecular reaction?

  • Question 04:

    The rate of a chemical reaction will increase with

  • Question 05:

    Reaction rate decreases if the frequency of collisions

  • Question 06:

    Why is the reaction below, unlikely to take place in a single, elementary step?

    A + 2B + C → Products

  • Question 07:

    Consider the reaction shown below that takes place in two, elementary steps that make up a more complex, overal reaction.

    Step 1: O3(g) + HO(g) → HO2(g) + O2(g) Step 2: HO2(g) + O(g) → HO(g) + O2(g)

    What is the molecurality of the second step?

  • Question 08:

    In a reaction where a very large proportion of the molecules involved have energies that are equal to or greater than the activation energy, it is observed that the reaction is still relatively slow. What is the most reasonable explanation for this?

  • Question 09:

    What is the molecularity of the elementary reaction shown below?

    2HI → H2 + I2

  • Question 10:

    Which of the following will be found at the highest energy on a reaction enthalpy profile?
