  • Q1
    Which of the following would NOT increase the rate of a chemical reaction?
    increasing the concentration of the products
    increasting the temperature
    adding a catalyst
    increasing the surface area
  • Q2
    How does adding a catalyst increase the rate of a reaction?
    Adding a catalyst lowers the activation energy required for a reaction to ocurr
    Adding a catalyst increases the concentration of the substances involved in a reaction
    Adding a catalyst increases the kinetic energy of the reactants
    Adding a catalyst allows the substances to move slower and more carefully so the reaction proceeds more efficiently
  • Q3
    Which of the following reaction systems will proceed most quickly? (assume all other factors are constant)
