conceptual, lengthy but not that difficult. long: -limitations of stoichiometry -stopped flow mechanism -fractional distillation. short: - steps of reaction mechanism -effect of phase, solvent, and surface area on reaction rate -colloid properties -which properties are used to measure the reaction rate mcq: almost saray topics mai aak ya do mcq thay, spectrometry, colloid, order of reaction, reaction rate, reaction kinetics, le-char law, Arrhenius equation, half life, gibs , energy, spontaneous reactions, enthalpy, activation energy, enzymes, effects on biomolecules....etc best of luck
