begin mathsize 36px style k equals A. e to the power of bevelled fraction numerator E subscript A over denominator R. T end fraction end exponent end style

K = Rate Constant;  A = Frequency Factor;  EA = Activation Energy;  T = Temperature; R = Universal Gas Constant ;





Temperature has a profound influence on the rate of a reaction. Arrhenius showed that the rate constant (velocity constant) of a reaction increases exponentially with an increase in temperature. Here 'A' is called the 'pre-exponent factor' or the 'frequency factor' and EA is the activation energy of the chemical process (reaction).
