Given the balanced equation representing reaction:

N2 + energy ==> N + N

Which statement describes this reaction?

( I) Bonds are broken, and the reaction is endothermic.

(2) Bonds are broken , and the reaction is exothermic.

(3) Bonds are formed, and the reaction is endothermic.

(4) Bonds are formed, and the reaction is exothermic.

Verified Answer :

( I) Bonds are broken, and the reaction is endothermic.
(2) Bonds are broken , and the reaction is exothermic.
(3) Bonds are formed, and the reaction is endothermic.
(4) Bonds are formed, and the reaction is exothermic.

Answer: Option (1) is the correct answer.

Explanation:

In a \(N_{2}\) molecule, the nitrogen atoms are bonded together by triple bond.

Therefore, in order to break this triple bond high heat or energy has to be provided.

Thus, the reaction \(N_{2} + energy \rightarrow N + N\) shows that N triple bond N is broken down as energy is absorbed by \(N_{2}\) molecule.

Hence, we can conclude that in the given reaction bonds are broken, and the reaction is endothermic.
