The rate of chemical reaction are strongly affected by temperature . Arrhenius (1889) gave following relation between rate contant and temperature . `k=Ae^(-E_(a)//RT)\" \".....(i)` This equation is called Arrhenius equation. The constant \'A\' is caleld Arrhenius of pre-exponential factor. Logarithm of equation (i) given : `log_(10)k=log_(10)A(E_(a))/(2.3030RT)\" \".....(ii)` The rate constant for a reaction is . `log_(10)\"sec\"^(-1)=14-(1.25xx10^(4)K)/(T) \" \".....(iii)` The pre-exponential factor or frequency factor of the reaction under consideration is :
