- How do you find the order for [O2]?Sketch an energy diagram for a two-step reaction in which both steps are exergonic and in which the second step has a higher-energy transition state than the first. Label the parts of the diagram correspoding to reactant, product, intermediate, overall ΔG‡, and overall ΔG°.Q7. Some spontaneous reactions take 20 million years for half of the reactants to be converted into products while other reactions take 10 seconds. What is the basis for this difference in rate? A. Reactions take longer the closer their ΔG is to zero. B. The rate is dependent upon the concentration of substrate molecules. C. Reactions where substrate molecules can more readily reach the transition state occur faster. D. The rate of the reaction is dependent upon a supply of energy - thus coupled reactions that utilize ATP are the fastest.
