Calculating the Keq and ∆G from concentration. An enzymatic hydrolysis of fructose-1-p+ H2O <-> fructose + Pi was allowed to proceed to equalibrium at 25°C. The original concentration of fructose-1-p was 0.2 M, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.25 × 10^-5 M. Calculate the equalibrium constant for this reaction and the free energy of hydrolysis of fluctose-1-p
