WebTo get the bonds into a state that allows them to break, the molecule must be contorted (deformed, or bent) into an unstable state called the transition state. The transition state is a high-energy state, and some amount of energy – the activation energy – must be added in order for the molecule reach it. ... For endothermic reactions heat ... WebIf your reactions involve covalent bonds, I think the method that would be most relatable at that age is using bond energies: how much energy it takes to break each bond you need to come apart, and how much you get out from making the new bonds. This only gives an approximation, but it’s much easier to explain than some other approaches.

WebStep-by-step explanation. A reaction is considered endothermic if it results in the accumulation of energy, while an exothermic reaction is defined as one that results in the loss of energy. When bonds are formed, exothermic reactions occur, and when bonds are broken, endothermic reactions occur. WebJun 1, 2024 · Combustion of methane showing where chemical bonds are broken and formed in the reactants and products (©2024 Let’s Talk Science). What is important to know is that energy is needed to both make and to break bonds.To determine if a reaction is exothermic or endothermic, you have to compare the amount of energy needed to …

WebSep 17, 2014 · Bonds are both broken and made in chemical reactions but many biology teachers and textbooks state that "Breaking ATP bonds releases energy." In reactions bonds are broken and made. If the strength of the bonds formed exceeds the strength of the bonds broken the reaction is exothermic. WebEndothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.
