Unit 7 · Equilibrium

Chapter 7.2

The Reaction Quotient and the Equilibrium Constant

At equilibrium the concentrations can be anything, but one particular ratio of them is always the same number for a given reaction and temperature. That number is a property of the reaction itself.

By the end

  1. 01Write the reaction quotient in concentration or partial-pressure form, omitting solids and pure liquids
  2. 02Explain why Q approaches K and equals it at equilibrium
  3. 03Compute K_c or K_p from measured equilibrium concentrations or pressures
