Answer: The reaction is exothermic reaction as the energy of products is less than the energy of reactants.

Explanation: Exothermic reactions are defined as the reactions in which energy of the product is less than the energy of the reactants. The total energy is released in the form of heat and [tex]\Delta H[/tex] for the reaction comes out to be negative.

Labeling of the parts in the diagram:

A represents the activation energy which is the energy required by reactants to cross the energy barrier to get converted to products.

E represents the potential energy of the reactants.

B represents the activated complex.

D represents the potential energy of the products.

C represents the total enthalpy change of the reaction, which comes out to be negative for exothermic reactions.

Based on energy profile diagram , the reaction is exothermic because the energy content of the reactants is greater than that of the products.

Also, the various letters represent the following:

  • A represents the activation energy
  • B represents the activated complex
  • C represents the total enthalpy change of the reaction
  • D represents the potential energy of the products
  • E represents the potential energy of the reactants.
  • F represents the reactants
  • G represents the products

What is the information in the energy profile diagram of the reaction shown?

The energy profile diagram illustrates the path of energy changes that occur in a reaction as well as the energy content of the reactants and products.

The letters shown in the diagram represents the following:

  • A represents the activation energy which is the minimum energy that reactant molecules must possess in order to form products.
  • B represents the activated complex which is intermediate state attained during the conversion of reactants into products.
  • C represents the total enthalpy change of the reaction.
  • D represents the potential energy of the products which is present in the chemical bonds of the products.
  • E represents the potential energy of the reactants which is the chemical potential energy present in the bonds found in the reactant.
  • F represents the reactants
  • G represents the products

The reaction is exothermic since the energy content of the reactants is greater than that of the products.
