Reaction is endothermic or exothermic
WebDistinguish between endothermic and exothermic reactions Key Points All chemical reactions involve the transfer of energy. Endothermic processes require an input of energy to proceed and are signified by a positive change in enthalpy. Exothermic processes release energy upon completion, and are signified by a negative change in enthalpy.

WebJun 16, 2024 · For a general reaction, search for standard enthalpy of formation of all reactants and products, multiply the values by stoichiometric coefficients and subtract the reactant values from the product values. If the result is negative, the reaction is exothermic. For the positive value, the reaction is endothermic. 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).
