How do you find k using reaction profiles? (quiz 2 prep #1)

Based on the workbook, I think you can only get a qualitative estimate of K (the equilibrium constant) (and thus the ratio of the rate constants, k/k')from a reaction profile (if it doesn't provide data) based on whether or not the formation of reactants or products is favored. So I think if the energy of the products is lower than that of the reactants, the forward reaction is favored and K>1 (so k>k'). If the energies are the same, K=1 because neither direction of reaction is favorable, and if the reactant energy is less than the product energy the reverse reaction is favorable and K<1 (so k<k').
