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: Heat is released. 1) Combustion: The burning of carbon-containing compounds uses oxygen, from air, and produces carbon dioxide, water, and lots of heat. For example, combustion of methane ( \text {CH}_4 CH4) can be represented as follows: 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. datamaster police
