Section 14.2- Le Chatelier's Principle

Question 1

any factor that changes the rate of either the forward or the reverse reaction will upset the equilibrium so that the rates are no longer equal

Answer 1

stress

Question 2

if the forward reaction occurs faster than the reverse reaction under such a stress the equilibrium is said to

Answer 2

shift to the right

Question 3

the reverse reaction occurs faster, the equilibrium is said to

Answer 3

shift to the left

Question 4

the rule used to determine the direction in which a given stress will cause an equilibrium to shift is

Answer 4

Le Chatelier’s Principle

Question 5

if a stress is applied to a system at equilibrium, the system will react in such a way that the stress is at least

Answer 5

partially offset

Question 6

under chemical reaction,

Answer 6

1. reactions are equal and opposite
2. concentrations are constant

Question 7

change because of Le Chatelier’s principle

Answer 7

1. concentration
2. pressure
3. temperature

Question 8

increasing the concentration of a given substance will

Answer 8

increase the rate of reaction

Question 9

decreasing the concentration of a given substance will _____________________________ in which it is a reactant

Answer 9

decrease the rate of reaction
