Gibbs Free Energy Calculation for Glucose Combustion

The combustion of glucose (C₆H₁₂O₆) in cellular respiration can be represented by the following balanced chemical equation:

C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O

The standard enthalpy change (ΔH_rxn) for this reaction is -2800 kJ/mol of glucose consumed. Considering the direct relationship between enthalpy, entropy, and Gibbs free energy, what will the Gibbs free energy change (ΔG_rxn) at 298 K for this process be, if the entropy change for the reaction is +500 J/(mol·K)?

Use the equation ΔG_rxn = ΔH_rxn - TΔS_rxn.
