It is possible to obtain entropy of activation using Eyring equation. This equation is of the form where:
*  = reaction rate constant
*  = absolute temperature
*  = enthalpy of activation
*  = gas constant
*  = transmission coefficient
*  = Boltzmann constant = R/N, N = Avogadro constant
*  = Planck's constant
*  = entropy of activation
This equation can be turned into the formThe plot of  versus  gives a straight line with slope  from which the enthalpy of activation can be derived and with intercept  from which the entropy of activation is derived.
