4. An important glycolysis pathway includes the reaction of glucose-6phosphate (G6P) to form fructose-6-phosphate (F6P) (G6P(aq) F6P(aq)).G298=1.7kJ. Is the reaction spontaneous under standard thermodynamic conditions? Most cells are not under standard thermodynamic conditions. (a) If G6P has a concentration of 120M and F6P has a concentration of 28M, what is the spontaneity of the reaction (spontaneous in forward direction, at equilibrium, or spontaneous in reverse direction)? (b) What are the concetrations of G6P and F6P at equilibrium if you have the starting conditions described in part a? 5. Draw sketches of reaction coordinate diagrams for the following scenarios (focus on the relative positions of reactants and products): (a) K is much larger than 1 (b) K is much smaller than 1 (c) There are many more reactants at equilibrium than products. (d) There are many more products at equilbirum than reactants
