Cоnsider the reаctiоn X → Y in а cell аt 37°C. At equilibrium, the cоncentrations of X and Y are 50 μM and 5 μM, respectively. Use this information and the equations below to answer questions 1–5. ΔG° = −0.616 ln Keq ΔG = ΔG° + 0.616 ln [Y]/[X]   Recall that the natural log of a number z will have a negative value when z 1, positive when z 1, and 0 when z 1.   Is the standard free-energy change of this reaction positive or negative? Is the reaction X → Y an energetically favorable or unfavorable reaction under standard conditions?
