SUMMATIVE TEST (GENERAL CHEMISTRY 2-2N OT) A. Given the equation, calcite the standard free energy change. Answer what is being asked? 3. 1. N2(g)+3112(g) --->2NH3(g) If AH = -92.2kJ and AS= -0.1987kJ/K, what is AG for the reaction at 475°C and at 5"C? Provide the answer in kJ. In each case, is the reaction spontaneous? 2. The enthalpy and entropy change of a reaction are -3.9 kJ/mole and +56.6 J/mole K respectively at 250 C. What is the free energy change in kJ/mole? Is this reaction always spontaneous, never spontaneous or does it depend on the temperature?
