  27. Question Twenty Three • What three things are necessary for a successful reaction to occur? • Reactant molecules must collide • The collision must occur with sufficient energy to get over the activation energy hump • The collision must occur with the proper orientation

  28. Question Twenty Four • What are four ways to speed up a reaction? • Increase concentration • Increase temperature • Increase pressure of a gaseous system • Add a catalyst • More Surface Area

  29. Question Twenty Five • How does increasing the temperature increase reaction rate? • Molecules have more energy and therefore there will be more collisions and the increased energy means a greater fraction of the molecules will have enough energy to get over the activation energy hump

  30. Question Twenty Six • What is entropy? • A measure of the disorder in a system

  31. Question Twenty Seven • How does adding a catalyst affect the reaction rate? • It speeds up a reaction by lowering the activation energy so that more molecules have sufficient energy to get over the activation energy.

  32. Question Twenty Eight • Which has more entropy, solid water or water vapor? Why? • Water vapor has more entropy because there is more disorder in the gaseous state than in the solid state due to the increased molecular motion of gases

  33. Question Twenty Nine N2 (g) + 3H2 (g)  2NH3 (g) DH = -230 kJ Which direction will the reaction proceed if: a. the pressure is decreased. left b. the reaction is cooled. right c. a catalyst is added. neither d. NH3 is added. left e. H2 is added. right f. some nitrogen is removed. left

  34. Question Thirty For the reaction below, which change would cause the equilibrium to shift to the right? • CH4(g) + 2H2S(g) ↔ CS2(g) + 4H2(g) DH = -43.0 kJ (a) Decrease the concentration of dihydrogen sulfide. Shift to the Left (b) Increase the pressure on the system. Shift to the Left (c) Decrease the temperature of the system. Shift to the Right (d) Increase the concentration of carbon disulfide. Shift to the Left (e) Decrease the concentration of hydrogen. Shift to the Right
