WebMar 8, 2024 · An exothermic reaction may be non-spontaneous if the reaction also leads to a decrease in entropy. Once temperature is above a certain point, this means the reaction becomes entropy-driven, causing the reaction overall to have a positive deltaGo. An online example I found of this is the combustion of methane. WebExothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. Endothermic reactions take in energy and the temperature of the surroundings decreases.

WebMar 16, 2014 · When the water is placed in a freezer, the water slowly loses heat to the surrounding cold air. The water molecules on losing energy begin to move slowly, come closer and pack close enough to change to ice. In this process, the water releases heat to the surroundings, so it is an exothermic process. When water lose energy, the individual ...
