A reaction is carried out at 25 °C with AH° = 20 kcal/mol and AS° = 25 cal/K-mol. (R : 8,314 J/K-mol or 1.987 cal/K-mol)Is the reaction exothermic or endothermic? Why? What does the value of the entropy tell about the reaction? Why? What is the equilibrium constant? Is the reaction spontaneous? Why?
