Chemical Equilibrium: Minimizing Free Energy



What is equilibrium?

Phase equilibrium-The state of balance between 2 opposing phases (dissolving and crystallization). This occurs when a solution is saturated.

REGENTS NOTE***These processes occur at the SAME RATES. The Concentration remains constant.

Notice after equilibrium is established (3 Ag+ and 3 Cl-) the crystallization and dissolving rates equalize. This is called a DYNAMIC EQUILIBRIUM. This implies that there is constant change in the particles but overall the concentration and the mass of the solid remains constant.


Chemical Equilibrium-The state of balance between 2 opposing reactions. Once equilibrium is established the Concentrations Remain CONSTANT and the Rates are EQUAL. "CON CON REqual"
