PHYSICAL CHEMISTRY – Formula Focus Section
Physical Chemistry is formula-driven. Therefore, revise formulas repeatedly. 1. Solutions (7 Marks) Important formulas:- Molarity = moles / volume (L)
- Molality = moles / kg solvent
- ΔTb = Kb × m
- ΔTf = Kf × m
- π = MRT
- van’t Hoff factor (i)
- E°cell = E°cathode − E°anode
- ΔG° = −nFE°
- E = E° − (0.0591/n) log Q
- Λm = κ × 1000 / C
- Nernst equation numericals
- Relation between K and E°
- Kohlrausch’s Law
Because of high weightage, this section is critical in your chemistry cheat sheet class 12 revision.
3. Chemical Kinetics (7 Marks) Key formulas:- k = 2.303/t log (A₀/A)
- t½ (First order) = 0.693/k
- Units of rate constant
- Order vs molecularity
- Graph-based numericals
INORGANIC CHEMISTRY – NCERT Based Direct Questions
Inorganic is memory-based. However, it is scoring if revised properly. 4. d- and f-Block (7 Marks) Revise:- Variable oxidation states
- Colour due to d–d transition
- KMnO₄ reactions
- K₂Cr₂O₇ reactions
- Lanthanoid contraction
- IUPAC naming
- Oxidation number
- Magnetic moment: μ = √n(n+2)
- VBT (inner vs outer orbital)
- Geometrical isomerism
- Linkage isomerism
