AP Chemistry / Unit 7: Equilibrium
7.1 Introduction to Equilibrium
Notes
At equilibrium, forward and reverse rates are equal, and concentrations stay constant (not necessarily equal).
- Equilibrium is dynamic: both reactions continue.
Practice
At equilibrium:
Dynamic balance.
On a concentration vs time graph, equilibrium is reached when:
Constant concentrations.
Equilibrium can be reached from:
Same $K$ either way.
