Unformatted text preview: HW 7 Sathasivan (49750) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points In a chemical reaction, transition-state species have free energies that are 1. lower than the reactants, but the same as the products. 2. higher than either the reactants or the products. correct 3. higher than the reactants, but lower than the products. 4. lower than the reactants, but higher than the products. 5. lower than either the reactants or the products. Explanation: 002 10.0 points If the enzyme phosphohexosisomerase is added to a 0.3 M solution of fructose 6- phosphate, and the reaction is allowed to proceed to equilibrium, the final concentra- tions are 0.2 M glucose 6-phosphate and 0.1 M fructose 6-phosphate. These data give an equilibrium constant of 2. What is the equi- librium constant if the initial concentration of fructose 6-phosphate is 3 M?...
