(10) WOC p. 155, Question 24. a) Increasing temperature will increase the rate of a reaction by giving molecules the ability to overcome the activation energy. b) Increasing concentration increases the rate of a reaction by providing more molecule collisions. c) Introducing a catalyst increases the rate of a reaction by decreasing the activation energy required to start a reaction. 3. (10) WOC p. 155, Question 32. When a reaction “shifts in favor of the reactants,” the equilibrium has been disturbed, and the new equilibrium has a greater proportion of reactants (and lesser proportion of products) than it did initially. 4.
