Chapter U5.11, Problem 9E

Interpretation Introduction

Interpretation : The correct option regarding exothermic reaction needs to be identified.

Concept Introduction : The total bond energy can be defined as the summation of individual bond energies of the bonds in the molecule.

If the energy value is positive, then the reaction is an endothermic reaction and if the energy value is negative, the reaction is an exothermic reaction.

Answer to Problem 9E

Option A is the correct answer.

Explanation of Solution

In an exothermic reaction, the energy value of the net reaction has a negative value.

In an exothermic reaction, more energy is required to make some new bonds in the products than the energy required to break all the bonds present in the reactants.

Conclusion

Out of the given four options, option A is the correct answer.
