The following reaction represents the oxidation of glucose

C₆H₁₂O₆(s) + 6O₂(g) ⇌ 6CO₂(g) + 6H₂O(l)
Consider the following data in this regard:
Substances $Δ G_{f}^{\circ}$ (kcal/mol)
C₆H₁₂O₆(s) –218
CO₂(g) –94
H₂O(l) –57
Based on the above data, the standard free energy change ( $Δ G^{\circ}$ ) for the oxidation of glucose is:
