WebFeb 28, 2024 · 2 C H 3 C O O H ( l) + ( N H 4) 2 C O 3 ( s) → C H 3 C O O N H 4 ( a q) + C O 2 ( g) + H 2 O ( l) This reaction is spontaneous despite being endothermic because the entropy change is sufficiently positive. I don't understand how the entropy change can effect the spontaneity of a reaction. WebSpontaneous reactions simply mean that the products will be lower in free energy than the reactants ( Δ G is negative). If Δ G is negative, then it is energetically favourable for the reaction to occur - in other words, there will be a release of energy due to the reaction.
