Which statement is true if the hrxn of a reaction is positive?

Question

What can be concluded about a reaction if the enthalpy change (ΔH_rxn) is positive?

Anonymous · Accepted Answer

When the heat of reaction is positive, then the reaction is an endothermic reaction. It means that the heat is into the system. The reaction to occur heat should be supplied into the system. It is not a spontaneous reaction since the process absorbs energy to reach the activation energy.

The correct answer is Option A.Explanation:Endothermic reactions are defined as the reactions in which potential energy of the reactants is less than the potential energy of the products. The total enthalpy change of the reaction comes out to be positive. Energy is absorbed during this reaction. Exothermic reactions are defined as the reactions in which potential energy of the products is less than the potential energy of the reactants. The total enthalpy change of the reaction comes out to be negative. Energy is released during this reaction.From the above information, the correct answer is Option A.

Answer : The reaction is endothermic in nature.Explanation : A system of reactants which absorbs heat from the surroundings in an endothermic reaction has a positive ΔH reaction value, as the enthalpy of the products is higher than the enthalpy of the reactants of the system.As the enthalpies of these reactions are greater than zero, they are called as endothermic reactions. Which absorbs the heat during the chemical reactions.

If the Hrxn of a reaction is positive then the reaction is endothermic reaction. In an endothermic reaction, heat is absorbed by the chemical reaction from the surrounding. Reactants + heat --> ProductsIn the activation energy diagram the heat of the products is greater than the heat of the reactants in an endothermic reaction.
