To determine whether the reaction is endothermic or exothermic based on bond energies, you need to compare the total bond energy of the reactants with that of the products.

  • If the total bond energy of the reactants is greater than that of the products, the reaction releases energy, making it exothermic.
  • Conversely, if the total bond energy of the reactants is less than that of the products, the reaction absorbs energy, making it endothermic.

Since the question does not provide the specific bond energies or a table to reference, we will rely on the general principles as outlined above.

From the provided options:

  1. The reaction is endothermic because the energy of each bond in the reactants is less than the energy of a bond in the products.
  2. The reaction is exothermic because the energy of each bond in the reactants is greater than the energy of a bond in the products.
  3. The reaction is endothermic because the total bond energy of the reactants is greater than the total bond energy of the products.
  4. The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products.

To choose the correct statement:

  • Look for the statement that correctly correlates the nature of the reaction (endothermic or exothermic) with the comparison of total bond energies of the reactants and products.

  • If the total bond energy of the reactants is greater, the correct answer would be the exothermic option.

  • If the total bond energy of the reactants is less, the correct answer would be the endothermic option.

You'll need the specific bond energies to determine the correct answer definitively, but based on typical chemical reasoning regarding bond energies, the following two options provide the most relevant conclusions:

  • The reaction is endothermic because the total bond energy of the reactants is greater than the total bond energy of the products.
  • The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products.

Select the one that fits your data best! If you have the bond energy values from the table, you can use those to finalize your answer.
