  • Q1

    Which of the following statements best describes the rate of a chemical reaction?

    It is the pressure exerted by the reactants during the process of chemical reaction.

    It is the speed in which the reactants are converted into a product.

    It is the amount of temperature needed to start a chemical reaction.

    It is the volume in which the reactant particles can occupy.

  • Q2

    A chemical change that occurs when two or more substances combine to form a new substance.

    Chemical Reaction


    Activation Energy

    Chemical Kinetics

  • Q3

    Catalysts generally react with one or more of the reactants to form a structure, which then reacts to form the final product. What do you call this structure?

    activated catalyst

    activated reactants

    activated products

    activated complex

  • Q4

    Which of the following best describes a catalyst?

    Adds to the concentration of the reactants in a chemical reaction.

    Increases the activation energy of reacting particles.

    Speeds up the process of a chemical reaction, without being consumed.

    Increases the temperature of reacting particles in chemical reaction.

  • Q5

    Which of the following conditions would speed up a reaction?

    Increasing the concentration of reactants

    Decreasing the temperature

    Using lumps instead of powder

    The mixture is not stirred

  • Q6

    Which of the following is NOT a key concept of the collision theory?

    particles must move slowly when they collide, otherwise the simply bounce off one another

    particles must collide in order to react

    particles must collide with proper orientation

    particles must collide with sufficient energy known as the activation energy

  • Q7

    Which of the following does NOT affect the rate of a chemical reaction?





  • Q8

    The rate of a chemical reaction normally

    increases as reactant concentration decreases

    increases as the surface area increases

    decreases as the temperature increases

    decreases when a catalyst is added

  • Q9

    Crushing a solid into a powder will increase the rate of reaction because:

    the activation energy will be lowered

    the particles will collide with more energy

    the powdered form has more surface area

    the orientation of colliding particles will be improved

  • Q10

    In general, as temperature increases, the rate of a chemical reaction

    decreases due to fewer collisions with proper molecular orientation

    increases due to an increase in the activation energy

    remains unchanged

    decreases due to a greater number of effective collisions

  • Q11

    True or False. If the reactant particles collide with less than the activation energy, the particles bounce back and no reaction will occur.

    True or False
  • Q12

    Catalysts permit reactions to proceed along a ___________energy path.



    none of these


  • Q13

    How is catalyst different from a reactant?

    Adding more catalyst slows down the rate of reaction.

    The catalyst is not used up in the reaction.

    The catalyst increases the activation energy of the reaction.

    Adding more catalyst speeds up the rate of reaction.

  • Q14

    If you used a gaseous reactant and a solid catalyst, this means the catalyst you used is a ___________.
