Rewrite the Eyring-Polanyi expression in a form that includes enthalpy and entropy instead of Gibbs free energy. b. Suppose that we are performing experiments on a bimolecular gas-phase reaction between A and B: A+B⇌[A∙B]‡→AB At 300 K, we measure kTST to be 2.425*10^-5 s-1. At 250 K, we measure kTST to be 1.370*10^-8 s-1. Use this data to compute the enthalpy and entropy of activation in J mol-1 and J mol-1 K-1, respectively.

Question
a. Rewrite the Eyring-Polanyi expression in a form that includes enthalpy and entropy instead of Gibbs free energy.
b. Suppose that we are performing experiments on a bimolecular gas-phase reaction between A and B:
A+B⇌[A∙B]‡→AB
At 300 K, we measure kTST to be 2.425*10^-5 s-1. At 250 K, we measure kTST to be 1.370*10^-8 s-1. Use this data to compute the enthalpy and entropy of activation in J mol-1 and J mol-1 K-1, respectively.
