Why is the dissolution of AgCl considered endothermic?

WebJun 6, 2016 · From an entropic point of view, this is bad. Rather than having two dissolved ions, we have one on the products’ side. Therefore, we can assume Δ S < 0, therefore T ⋅ Δ S < 0. Negating it gives a positive value. But the reaction is spontaneous, so Δ G < 0. This can only be true if Δ H is sufficiently negative to counteract the loss of entropy. Thermal decomposition (or thermolysis) is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. If decomposition is sufficiently exothermic, a positive feedback … mcv gym class schedule
