High Entropy Low Entropy ssolved in liquid = rate gas above liquid Dissolving Crystalizing ersions: 3 = 1 L 1 mL = 1 cm 3 cm 3 = 1 dm 3 1 L = 1000cm 3 Andrew Rosen Equilibrium : State of balance between two opposing reactions (same rate, not necessarily amounts), and it can be either physical or chemical (catalysts have no favoring; it’s equal distribution) H 2 O (s) = H 2 O (l) Solution Equilibrium: 1 – Gas in liquid 2 – Solid in liquid C 6 H 12 O 6(s ) = C 6 H 12 O 6(aq) Chemical Equilibrium: Achieved when concentration of reactants and products remains constant Le Chatlier: If a stress is applied to a system at equilibrium, the equilibrium will shift direction to relieve that stress 1 – Concentration N 2(g) + O 2(g) = 2 NO (g) Stress: Increased [N 2 ] Shift: Forward Result: [O 2 ] Decrease and [NO] Increases N 2(g) + O 2(g) = 2 NO (g) Stress: Decreased [O 2 ] Shift: Reverse Result: [NO] Decrease and [N 2 ] Increases N 2(g) + O 2(g) = 2 NO (g) Stress: Increased [NO] Shift: Reverse
