Respuesta :
The new substance will need more energy to form its chemical bonds than the old substance will release. Hence, option A is correct.
What is an endothermic reaction?
Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.
Endothermic reactions, in general, are those that absorb (or use) energy. In endothermic reactions, more energy is absorbed when bonds in the reactants are broken than is released when new bonds are formed in the products.
Normally, when a chemical bond is broken, energy is released in the process. The chemical bond formation also demands an energy input.
The energy that is supplied/released can come in varieties (such as heat, light, and electricity). The formation of chemical bonds following the absorption of heat from the environment characterizes endothermic processes.
When two chemicals react in an endothermic reaction the new substance will need more energy to form its chemical bonds than the old substance will release. Hence, option A is correct.
