Equilibrium: two opposing processes occurring at the same rate to achieve balance Players enter and leave the game, but… the same total number of players on field.
2
Club Equilibrium (200 max) 200 VIP 180 (20 max) 20 RateIN equal
Con-Con Requal Club Equilibrium (200 max) At Equilibrium: Concentrations: VIP (20 max) 200 180 constant Rates: 20 equal 200 (Club) RateIN 180 180 same people? equal 20 20 RateOUT 0 (VIP)

Con-Con Requal H2O(l) ⇄ H2O(g) Phase Change Equilibrium
4
Rate of Crystallization
Saturated Solution Equilibrium Rate of Solvation = Rate of Crystallization animation Con-Con Requal Animation: total moles of dissolved NaCl remains constant total moles of undissolved NaCl(solid) remains constant
5
Concentrations of prod’s/react’s remain constant, but not equal
Ratef(N2O4) Rateforward = Ratereverse Rater(NO2) Dynamic Equilibrium ⇄ N2O4(g) 2 NO2(g) Concentrations of prod’s/react’s remain constant, but not equal
