Question

Which statement is true about endothermic and exothermic reactions

Answer 1

Answer:

Endothermic reactions are such types of chemical reactions in which energy is absorbed. Exothermic reactions are such types of chemical reactions in which energy is released. The potential energy of the product is more than the potential energy of the reactants in an endothermic reaction.

Answer 2

Answer:

Endothermic

• Endothermic reactions are chemical reactions in which energy is absorbed. Product potential energy is lower than reactant potential energy.

• The reaction mixture will absorb heat from its surroundings. The reactants will have less energy than the products. More energy is absorbed than released when the bonds between the reactants are broken.

• During endothermic reactions, the temperature of the reaction mixture drops.

Endothermic

• When a reaction releases more energy than it absorbs, it is called exothermic.
• For exothermic processes, the statement that the products will have less energy than the reactants is always true.This is because in an exothermic process, the system's heat is discharged into the environment.
• The energy in the reactants is retained in the system, and the reactants also absorb energy from the environment.
