∆G ° rxn = ∆G ° f [products] - ∆G ° f [reactants] Entropy and Disorder Gibbs Free Energy stuff Van’t Hoff Equation ln(K 2 / K 1 ) = (∆H ° rxn / R) * [ (T 2 - T 1 ) / (T 1 *T 2 ) ] Chemical Equilibrium Equilibrium and Thermodynamics Le Chatelier's Principle K c = ([X] x *[Y] y ) / ([A] a *[B] b ) K P = K C (RT) deltaVgas Acids and Bases Strong acids and bases Strong acids & bases completely dissociate in aqueous solutions pH and acidity pH = -log([H 3 O + ]) pOH = -log([OH - ]) pH + pOH = 14 K w = [H 3 O + ] [OH - ] = 1.0 * 10 -14 Ka and acid strength K a = [H 3 O + ] [A - ] / [HA] Acids with large values of K a are stronger acids than acids with smaller values of K a K b = [OH - ] [HA] / [A - ] K a * K b = K w pK a + pK b = 14 Buffers A buffer is made from a mix of a weak acid and its conjugate base (or vice versa)

A buffer solution suppresses a change in pH when a small amount of either an acid or a base is added Henderson-Hasselbalch equation pH = pK a + log([base] 0 / [acid] 0 Quantum Theory Electromagnetic Spectrum De Broglie Wavelength λ = h/mv Azimuthal Quantum Number Shape of the orbital Magnetic Quantum Number Spatial orientation Pauli Exclusion Principle None can have the same set of quantum numbers Hund’s rule
