Is an ice pack an endothermic reaction
Web30 nov. 2016 · An endothermic chain reaction is not possible because of this equation: Δ G = Δ H − T × Δ S. Where ΔG is the change in Gibbs free energy, which must be a negative number for spontaneous reactions (those that can go on without people helping along) ΔH is the change in enthalpy, in endothermic reactions, it is positive. Web13 aug. 2024 · Endothermic and exothermic reactions can be thought of as having energy as either a reactant of the reaction or a product. Endothermic reactions require energy, so energy is a reactant. Heat flows from the surroundings to the system (reaction mixture) …
