Unformatted text preview: D B E C G energy F H A I reaction progress What letter represents the starting material for the forward reaction? How many steps occur during this reaction? A 4 (A to C, C to E, E to G, G to I) 3 (C, E, G valleys in the course of rxn) How many intermediates for during this reaction? What letter(s) represent transition state(s)? What points must be used to determine ΔG? B, D, F, H I - A (difference) ΔG here is <0 4 How many energies of activations, Ea, must be overcome in the forward reaction? What is the rate determining step in the forward reaction? C to E - highest transition energy overall is RDS forward and reverse F-E (the difference) B-C (dif.) What points must be used to determine the Ea for step E--> G? What points must be used to determine the Ea for step C --> A (reverse reaction)? In the forward reaction, which step would have the lowest kr? What is the Keq for this reaction? kr depends on Ea A-->C is highest Ea (Keq >1), always matches ΔG ...
