pychu [463]

All of the energy from the reactants will be lost to the surroundings.The energy found in the reactants remains in the system, and the reactants also take energy from the

surroundings is true of energy in reactants during endothermic reaction.

<h3>What is Endothermic reaction?</h3>

Endothermic reaction is a reaction in thermochemistry where the reactants absorb heat from the surrounding to form the products.

In an endothermic reaction, the products have more energy than the reactants, that is they absorbed more energy. The reactants have less energy,that is they loss energy . Therefore, the change in enthalpy is positive, heat is absorbed from the surroundings during the reaction.

Therefore, All of the energy from the reactants will be lost to the surroundings.

The energy found in the reactants remains in the system, and the reactants also take energy from the

surroundings is true of energy in reactants during endothermic reaction.
