Consider the reaction glycerol(aq) + HPO42-(aq) ↔ DL-glycerol-1-phosphate2-(aq) + H2O(l). The equilibrium constant for this reaction at 37oC is 0.012, and the value of ∆rG0 at 25oC is 9.37 kJ. Given this information, what is the equilibrium constant (Keq) for the reaction at 25oC, and what is the value of ∆rH0 for the reaction? (You may assume that the ∆rH0 of the reaction is independent of temperature.)
