NEB Class 12 Chemistry · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

General and Physical Chemistry

  • Define and apply the mole concept, molar volume, and stoichiometric calculations to limiting-reagent problems

  • Balance ionic and redox equations using oxidation-number and half-reaction methods in acidic and basic media

  • Solve numerical problems on equivalent weight, normality, and molarity including dilution and titration stoichiometry

  • State and apply the gas laws and the ideal gas equation to calculate partial pressures in mixtures

Your checkpoint

A handwritten problem set of 30 solved numericals (mole concept, redox balancing, solution concentration, gas laws) with each final answer checked against units

Week 2

General and Physical Chemistry

  • Derive and apply rate laws to determine order and rate constant from given concentration-time data

  • Explain collision theory and the effect of temperature, catalyst, and surface area on reaction rate

  • Apply Le Chatelier's principle to predict the shift in equilibrium for changes in concentration, pressure, and temperature

  • Calculate pH, pOH, and buffer action for strong and weak acid-base systems

Your checkpoint

A one-page summary sheet of kinetics and equilibrium formulas plus 10 worked numericals on rate constant, Ka/Kb, and pH

Week 3

General and Physical Chemistry

  • Assign oxidation states and identify oxidizing and reducing agents in given reactions
