• Molecularity :
• The number of atoms, ions or molecules of the reactant that take part in the reaction and which experience collision with each other so that the reaction results, it is called molecularity
• Hence, the orders of reactions and molecularities of bimolecular, trimolecular and elementary reaction are same.
• The possibility of collision of three or more molecules with one another and to result in the reaction is less.
 
 The molecularity more than three is not seen.

• Pseudo – unimolecular or Pseudo first order reaction :
• Those reaction which are not truly of the first order but under certain conditions become reactions of the first order. Examples :
(i) Hydrolysis of ethyl acetate.
(ii) Hydrolysis of cane sugar.
 
• Determination of order of reaction :
Methods : (i) Intial rate method
(ii) Integrated rate equation method or Graphical method
(iii) Half life method
(iv) Ostwald’s isolation method
 
• Ostwald’s Isolation method :
• In certain reaction there is involvement of more than one reactants. In this method, the concentration of other reactants in comparison to one reactant is taken in very large proportion.
The reaction rate will be indicative with respect to reactant with less concentration because the concentration of other reactants remain almost constant.
• Half life method :
• The time taken for half of the reaction to complete.
• It is very simple method.

•  Effect of catalyst :
• The main function of catalyst is decrease the activation energy, bring energy barrier down and increases the rate of reaction.
• Equilibrium constant (K) is not changed.
• Rate of reaction increases.
