Rate of Chemical Reaction |
Average and instantaneous, with graphs, SI unit, rate of a reaction expressed as rate of change in molar concentration of reactants and products using balanced equation |
Factors Influencing Rate of a Reaction |
Factors affecting rate of a reaction, dependence of rate on concentration – rate expression (rate law), specific rate constant, order, units for rate constant of zero, first and, second order reactions. Molecularity – uni, bi and termolecular reactions – examples. |
Integrated Rate Equations |
Derivation of integrated rate equation for the rate constant of zero and first order reactions, graphs for zero and first order reactions-analysis, half-life – derivation of relationship between t1/2 and k for zero and first order reactions. Numerical problems on first order and half-life, Pseudo first order reaction- examples. |
Temperature Dependence of the Rate of a Reaction |
Arrhenius equation – activation energy, energy distribution curve showing temperature dependence of the rate of the reaction, problems based , graph of ln with intercept and slope. Effect of catalyst, explanation with graph. |
Collision Theory of Chemical Reactions |
An elementary idea of collision theory, criteria for effective collision – threshold energy and orientation factor. |
