8. For an isomerization reaction A B both the forward and reverse reaction are first order, with rate constants of 20 s^-1 and 10 s^-1 respectively at 350 K. a) Use TST to calculate the activation free energies for the forward and reverse reactions. b) Calculate the equilibrium constant and standard Gibbs free energy of reaction. 6. Transfer RNA exists in two forms that are in equilibrium A B, with equilibrium constant K = [B]eq/[A]eq = 10.0 at 40 degree C. A 10 mu M solution of tRNA is very rapidly heated from 37 degree C to 40 degree C and a relaxation time for reaching the new equilibrium of tau = 3 ms is measured.a) Find the rate constants for the forward and reverse reactions for tRNA isomerization. What temperature do these values correspond to? b) If we double the tRNA concentration, will the rate constants and relaxation time change or stay the same?
