An enzymatic hydrolysis of fructose-1-phosphate, fructose-1-P + H20 fructose + Pi was allowed to proceed to equilibrium at 25°C. The concentrations used in the reaction were lower than typical because a delicate enzyme was used - this is a typical modification used by biochemists that are valid for biochemical standard state (in this context). The original concentration of fructose-1-P was 0.2M, but when the system had reached equilibrium the concentration of fructose-1-P was only 6.52 x 10 5 Which of the below values comes closest to representing the free energy of hydrolysis of fructose-1-P?
