Half life of a reaction The half life of a reaction is the time in which the concentration of a reactant is reduced to one half initial concentration t1/2 = 0.693/k Temperature dependance of the rate of a reaction : For a chemical reaction with rise in temperature by 10 degree the rate constant is nearly doubled K = Ae-Ea /Rt A- Arrehenius factor R- Universal gas constant Ea- activation Energy The energy required to form intermediate called activated complex is known as activation Energy
