Consider the conversion of glucose to ethanol and carbon dioxide at a constant pressure of 1 atm and 25 °C. Thermodynamics parameters values are given in the table below. C6H1206 (s)→→ CH₂CH₂OH (1) + 2 CO₂ (g) Glucose (s) Ethanol (1) Carbon dioxide (g) S (J. K-¹ mol-¹) 212.1 160.7 213.7 -) Calculate AHOIXI rxn AGO (kJ/mol) -910.5 -174.1 -394.4 ) Calculate the Gibbs free energy change AGº for the conversion of glucose to ethanol and CO₂ at 25 °C. -) Suppose 0.5 mole of glucose is completely converted to ethanol and carbon dioxide at 25 °C. What is the amount of heat q evolved in this process? Explain. 1) If this reaction is performed at a pressure of 1 atm and 0 °C, will the reaction be more favorable, less favorable, or stay the same as the reaction performed at a pressure of 1 atm and 25 °C? Explain.
