WebSep 12, 2024 · As I understand the chemistry though, adding heat to an exothermic reaction should slow the reaction and effectively take longer for the joint to cure. Higher temperature means higher reaction speed, due to higher molecular kinetic energy. What changes for exothermic vs. endothermic reactions is their equilibrium point, not their speed. WebThanks that covers a lot. I suppose if the surrounding temperature were significantly high then heat will still be emitted(so still just as exothermic), but if it were super high then after the heat is emitted it'd get reabsorbed, and it's just boil and then you'd have an endothermic state of matter transition taking place at the same time as the exothermic chemical …

WebNov 24, 2016 · Re: Exothermic and Endothermic. If the reaction requires heat (endothermic reaction) to form more products, then the reaction will shift to the right favoring more product formation. If the reaction gives off heat (exothermic reaction) while forming product, then the reaction will shift to the left favoring reactant formation. I hope this helps! WebIf the reaction is exothermic, we need to decrease the temperature to favor the products, because the reaction generates heat. Raising temperature for exothermic reactions, or lowering temperature for endothermic reactions, causes the reaction to go backwards, assuming the reactions are reversible.
