Unit 7.9: Introduction to Le Châtelier’s Principle
Use Le Châtelier’s Principle to determine the shift in a system in
response to a stress.
-
If concentration of a reactant is increased, predict the direction of
the shift.
-
Explain how Le Châtelier’s principle applies when pressure is changed
in a gaseous reaction.
Describe the change in physical properties after a system responds to
stress (color, temperature, etc.).
-
How does the color of a solution change when equilibrium shifts in
Fe3+/SCN− system?
-
Explain why temperature changes can be observed during an exothermic
reaction when stressed.
