Question

34 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.

Answer 1

(1) Bonds are broken, and the reaction is endothermic is the best answer.

From a single molecule of N2, bonds are broken to form two N atoms. The system takes in energy, which is endothermic.

Hope this helps~
