  • Question 01:

    A reaction that is considered to be fast, is likely to have which of the following characteristics?


  • Question 02:

    Which of the following changes in conditions will definitely result in an increase in the rate of a reaction?


  • Question 03:

    Increasing the temperature of a reaction increases the rate. Why?


  • Question 04

    In a reaction involving gases, which list contains factors that ALL contribute to the rate?


  • Question 05:

    In a reaction that involves solid magnesium carbonate, it is observed that when the carbonate is ground into a fine powder, that the reaction occurs at an increased rate. What is the best explanation for this observation?


  • Question 06:

    In the reaction between zinc and hydrochloric acid (below) it is found that the rate of production of hydrogen over time, decreases. What is the best explanation for this observation?

    Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)


  • Question 07:

    Decreasing the volume of a vessel that houses a gaseous chemical reaction that ultimately goes to completion, will have which of the following effects, and for what reason?


  • Question 08:

    When solid zinc metal reacts with an aqueous solution of hydrochloric acid, which factors are relevant in determining the rate of the reaction?


  • Question 09:

    When the temperature of a reaction mixture of gases is increased, the Maxwell-Boltzmann distribution of energies is observed to shift. What can be said of the total area underneath the distribution curve for the higher temperature, when compared to the lower temperature?


  • Question 10:

    Changing the pressure of a reaction that takes place in the gaseous phase has which effects?
