Answer:
The correct option is: Br₂--------->2 Br(g)
Explanation:
Bond dissociation is a process in which energy is applied to break a chemical bond between the atoms of a molecule to give free atoms.
In the given reaction: Br₂-------->2 Br(g)
The covalent bond in Br₂ molecule dissociates to give two moles of bromine atoms. Therefore, it is a bond dissociation reaction.
