The rate of reaction ((dx)/(dt)) varies with nature, physical state and concentration of reactants, temperature, exposure to light and catalyst, whereas rate constant (K) varies with temperature and catalyst only. The rate constant K is given as K=Ae^(-E_(a)//RT) where A is Arrhenius parameter or pre-exponential factor and E_(a) is energy of activation. The minimum energy required for a reaction is called threshold energy and the additional energy required by reactant molecules to attain threshold energy level is called energy of activation. For a chemical reaction: Ararr Product, the rate of disappearance of A is given by: (-dC_(A))/(dt)=K_(1) (C_(A))/(1+K_(2)C_(A)) . At low C_(A) , the order of reaction and rate constants are respectively:
