Correct answer: The definition of an endothermic reaction is that the products have higher energy than the reactants, resulting in a positive enthalpy of reaction. For the reaction to run, there must be an input of energy.
An exothermic reaction is a reaction that potential enthalpy of the products is less than the reactants whereas in an endothermic reaction the enthalpy of products is greater than that of the reactants. Exothermic reactions release energy when proceeding but endothermic reactions need to absorb energy to proceed.
Which statement is true of energy in reactants during an endothermic reaction? The energy found in the reactants remains in the system, and the reactants also take energy from the surroundings.
Which statement is true concerning endothermic reactions? The change in enthalpy is equal to the energy absorbed by the reaction.
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.Dec 16, 2020
Which statement(s) is/are TRUE about energy and exothermic reactions? Energy is involved in ALL chemical reactions. Some energy is released in the course of all chemical reactions. A reaction is exothermic if more energy is released than absorbed by the reaction.
Correct answer: The opposite is true for exothermic reactions: the products have lower energy than the reactants, enthalpy of reaction is negative, and heat is released.

An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur. A hallmark of this type of reaction is that it feels cold.
In a chemical reaction, when energy is being absorbed, it is said to be endothermic. For example when we are boiling water on a stove, the water is continuously absorbing the heat from the stove. -Generally when we cook things it is an endothermic reaction, as food needs heat to cook.
Endothermic Processes Melting ice cubes. Melting solid salts. Evaporating liquid water. Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.Apr 9, 2020
Fusion, vaporization, and sublimation are endothermic processes.
