Endothermic Reactions: Definition, Example & Diagram
WebNov 27, 2024 · Why dissolution of ammonium chloride is endothermic reaction? At room temperature (T = 300K), dissolution of ammonium chloride is an endothermic process, because the solution feels colder as the solid NH4Cl dissolves in water and absorbs energy from water to do so. Therefore the enthalpy of dissolution is POSITIVE. WebEndothermic Reactions are chemical reactions that absorb heat from the surroundings they occur in. Dissolving ammonium chloride in water is an example of an endothermic reaction. Endothermic processes include cooking an egg, melting ice cubes, etc. In an endothermic reaction, the potential energy of the product is higher than that of its … WebFrozen Board: An endothermic reaction.
