Important Topics to be completed before the examination.

  • Meaning of Chemical Kinetics – slow and fast
    reactions. 
  • Rate of a reaction – average and
    instantaneous rate (graphical representation). 
  • Factors affecting rate of reaction: surface area,
    nature of reactants, concentration, temperature,
    catalyst, and radiation.
  • Order and molecularity
    of a reaction, rate law, and specific rate constant.
