Endothermic vs Exothermic Reactions ChemTalk

WebMar 16, 2024 · Hello! In terms of endothermic vs exothermic reactions, I usually think of the change of enthalpy throughout the reaction. This includes exothermic equations releasing energy to end up with a negative enthalpy and endothermic equations obtaining energy to end up with a positive enthalpy. Energy is often required to break bonds as well. WebJul 23, 2024 · If the enthalpy change listed for a reaction is negative, then that reaction releases heat as it proceeds — the reaction is exothermic ( exo- = out). If the enthalpy change listed for the reaction is positive, then that reaction absorbs heat as it proceeds — the reaction is endothermic ( endo- = in). In other words, exothermic reactions ... chinese food by post
