7. Consider the following data: AH (kJ/mole) AG (kJ/mole) C₂H₂(g) H₂O(1) -84.7 -285.9 -32.9 -237.2 CO₂(g) -393.5 -394.4 a) Calculate the entropy change for the combustion of 1.0 mole of C₂H₂(g) at 25°C. b) Are the products more or less ordered than the reactants at 25°C? c) Is the reaction spontaneous at 25°C? d) What is the maximum amount of useful work which can be obtained from the process at 25°C? e) If the process is carried out irreversibly at 25°C, under constant volume, what is the heat flow? f) If the process is carried out irreversibly under constant pressure at 25°C, what is the heat flow? g) What is the heat flow if the process is carried out reversibly at 25°C? h) If the process occurs under constant pressure at 25°C, what is the PAV work? 7.
