Webspontaneous reactions. occur in nature under a given set of conditions. occur when the products possess a lower energy (enthalpy) and a more random, distorted state (entropy) enthalpy (ΔH) most spontaneous reactions are exothermic. endothermic reactions may occur spontaneously when temperature is increased above a certain point. entropy (ΔS) WebChemistry. Chemistry questions and answers. The spontaneity of a reaction depends both on the enthalpy change, Delta H, and entropy change. Delta S. Reactions that release energy produce more stable products, and the universe tends toward disorder. Thus, an exothermic reaction with a positive entropy change will always be spontaneous.

WebMay 30, 2024 · If heat flows into the surroundings (i.e., when a reaction is exothermic) the random motions of the molecules in the surroundings increase. Thus, the entropy of the surroundings increases. The second law of thermodynamics states that the total entropy of the universe always increases for a spontaneous process.

WebBeing spontaneous doesn’t necessarily mean, however, that the reaction is exothermic. Highly exothermic reactions tend to be spontaneous, but weakly exothermic or endothermic reactions can be spontaneous under the right conditions. In other words, endothermic reactions can be spontaneous just like exothermic reactions can be non … 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.
