In this video, Mr. Krug shows students what thermodynamically-favored processes are, sometimes called spontaneous processes. He shows how ΔH and ΔS values for a reaction help determine which forces, if any, will drive a chemical reaction. He also shows how to determine under what conditions a reaction will be spontaneous, or thermodynamically-favored.
