Hydrolysis of 1 M Glucose 6-Phosphate Catalyzed by Glucose 6-Phosphatase

Hydrolysis of 1 M glucose 6-phosphate catalyzed by glucose 6-phosphatase is 99% complete at equilibrium (ie, only 1% of the substrate remains) . Which of the following statements is most nearly correct? (R = 8.315 J/mol·K; T = 298 K)

A) ΔG^0' = −11 kJ/mol
B) ΔG^0' = −5 kJ/mol
C) ΔG^0' = 0 kJ/mol
D) ΔG^0' = +11 kJ/mol
E) ΔG^0' cannot be determined from the information given
