WebJan 30, 2024 · An endothermic reaction occurs when the temperature of an isolated system decreases while the surroundings of a non-isolated system gains heat. Endothermic reactions result in an overall positive heat of reaction ( qrxn > 0 ). Exothermic and endothermic reactions cause energy level differences and therefore differences in … WebWhich of the following comparisons or contrasts between endergonic and exergonic reactions is false? a.Endergonic reactions have a positive ∆G and exergonic reactions have a negative ∆G. b.Endergonic reactions consume energy and exergonic reactions release energy. c.Both endergonic and exergonic reactions require a small amount of …
