THE THERMODYNAMICS OF POTASSIUM NITRATE …
faculty.uca.eduto dissolve (endothermic), and negative if heat is released for KNO 3 dissolving in water (exothermic). The ΔG can be used to determine the spontaneity of KNO 3 dissolving process: negative ΔG means the process is spontaneous while positive ΔG means the process is nonspontaneous.
Experiment 9: Enthalpy of Formation of Magnesium Oxide
www.bc.eduvs. time plot for a calorimetric experiment in which the reaction was exothermic. After the initial sharp rise in temperature when the reaction is begun (at time of mixing, t = 0 seconds), the temperature begins to decrease due to heat loss from the calorimeter. As the temperature equilibrium becomes complete, the loss becomes steady and the
