However, the equilibrium has been pushed to the reactants thus signifying the reaction is exothermic. But this assertion is on the assumption that the forward reaction is exothermic. kaill wheatley

Exothermic or endothermic? Classifying reactions Experiment

WebMar 1, 2024 · The opposite of an endothermic process is an exothermic process, one that releases, "gives out" energy in the form of heat. Thus in each term (endothermic & exothermic) the prefix refers to where heat goes as the reaction occurs, though in reality it only refers to where the energy goes, without necessarily being in the form of heat. italics … WebKey Points. When a chemical reaction happens, energy is transferred to or from the surroundings. When energy is transferred to the surroundings, this is called an exothermic reaction and usually ... WebSince heat left the system, the sign of q r e a c t i o n is negative, and the reaction is exothermic. As a teacher, I have found that getting system boundaries and the signs right is one of the biggest problems students have.
