Given the balanced equation representing a reaction:O2 --> O + O
What occurs during this reaction?
(1) Energy is absorbed as bonds are broken.

(2) Energy is absorbed as bonds are formed.

(3) Energy is released as bonds are broken.

(4) Energy is released as bonds arc formed.

Answers

In the equation given above, a molecule of oxygen breaks into two atoms of oxygen showing that the bond is being broken. When bonds break, energy is absorbed and when bonds are formed energy is released. Hence, the answer to this question is (1).
