Hydrolysis of 1 M Glucose 6-Phosphate Catalyzed by Glucose 6-Phosphatase $\Delta$

Hydrolysis of 1 M glucose 6-phosphate catalyzed by glucose 6-phosphatase is 99% complete at equilibrium (i.e. ,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) ( $\Delta$ G'° is -11 kJ/mol.)
B) ( $\Delta$ G'° is -5 kJ/mol.)
C) ( $\Delta$ G'° is 0 kJ/mol.)
D) ( $\Delta$ G'° is +11 kJ/mol.)
E) ( $\Delta$ G'° cannot be determined from the information given.)
