The Gibbs Phase Rule is:

F = C - P + 2

It is used to describe the variability of a system, or how many properties need to be known to define the system. This article goes into more detail regarding what the Gibbs Phase Rule is and what it means.

• Note: The [+2] term accounts for temperature and pressure. If temperature and pressure are known, then we can omit the [+2]. If one is known, then we can use [+1].

Test your understanding: How many properties must be known to define a system composed of solid A and liquid B at 1 atm?

This worksheet may help you review Le Chatelier's Principle. You can use the answer key on page 2 to check your work!

Test your understanding:

• How does the equilibrium shift when products are added? When reactants are added?

  • When a pure solid is added? When a pure liquid is added?

• How does the equilibrium shift when the system is heated for an exothermic reaction? For an endothermic reaction?

• How does the equilibrium shift when the pressure is increased? When the pressure is decreased?
