For the coupled reactions given below
\[
\begin{array}{ll}
\text { Glucose 6-phosphate }+\mathrm{H}_{2} \mathrm{O} \rightarrow \text { Glucose }+\mathrm{Pi} & \text { (Reaction 1) } \\
\text { ATP }+ \text { Glucose } \rightarrow \mathrm{ADP}+\text { Glucose 6-phosphate } & \text { (Reaction 2) }
\end{array}
\]
the standard free energy change of ATP hydrolysis at $25^{\circ} \mathrm{C}$ is $\qquad$ $\mathrm{kJ} / \mathrm{mol}$.
The equilibrium constants for Reaction 1 and Reaction 2 are 360 and 800, respectively; Gas constant $R=8.314 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$.
(Round off to two decimal places)
