- Physical: Nernst Eq: Ecell = E°cell - (0.059/n)log Qc; First Order kinetics: k = (2.303/t)log(a/a-x); Colligative properties depend on number of solute particles.
- Inorganic: Lanthanoid contraction leads to similar atomic radii for 4d and 5d series. Spectrochemical Series: I⁻ < Br⁻ < Cl⁻ < F⁻ < OH⁻ < H₂O < NH₃ < en < CN⁻ < CO.
- Organic: SN1 reactivity order: 3° > 2° > 1°; SN2 order: 1° > 2° > 3°. Acidity: Carboxylic acids > Phenols > Alcohols. Basicity of amines (aqueous): (CH₃)₂NH > CH₃NH₂ > (CH₃)₃N > NH₃.
