Derivation of the Erying Equation Erying equation (Eq. 1) is important in physical organic chemistry, based on Erying equation, by studying the temperature-dependency of the reaction rate constants, the information of the transition state of the reaction can be obtained, such as the activation enthalpy (H) and activation entropy ( S ). Based on the following diagram, please derivate the Erying equation (kobsd is the reaction constant, Tis the temperature. Ris the gas constant. kB is the Boltzmann constant): In(kobsd/T) = (-AH" /R) (1/1)+AS /R+In(kb/h) (1) Equilibrium Cont ** Reaction rate const B! XO XX X 1 A is the starting material. Bis the product. It is known that the reaction rate constant for the transition state to form the product is: k" = KAT h
