Given the balanced equation representing a reaction:
br2 + energy ==> br + br
which statement describes the energy change and bonds in this reaction?
(1) energy is released as bonds are broken.
(2) energy is released as bonds are formed.
(3) energy is absorbed as bonds are broken.
(4) energy is absorbed as bonds are formed.

3 is the right answer because, (1) 1 reactant "broke into" 2 products in the chemical equation (broken), and (2) energy absorbs when a chemical breaks into several parts.

In this reaction energy taken to use for breaking down the bonds so the answer is (3) Energy is absorbed as bonds are broken :)))
i hope this be helpful
