Question Twenty Two

0What three things are necessary for a successful reaction to occur?0 Reactant molecules must collide0 The collision must occur with sufficient energy to get

over the activation energy hump0 The collision must occur with the proper orientation

Question Twenty Three

0What are four ways to speed up a reaction?0 Increase concentration0 Increase temperature 0 Increase pressure of a gaseous system0 Add a catalyst0 More Surface Area

Question Twenty Four

0How does increasing the temperature increase reaction rate?0 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

Question Twenty Five

0What is entropy?0 A measure of the disorder in a system

Question Twenty Six

0How does adding a catalyst affect the reaction rate?0 It speeds up a reaction by lowering the activation

energy so that more molecules have sufficient energy to get over the activation energy.

Question Twenty Seven

0Which has more entropy, solid water or water vapor? Why?0 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

Question Twenty Eight

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
