Question

From the given reactions, which process represents the bond dissociation?

BR(l)------->Br2

Br2--------->2Br(g)

2BR(g) + 1e----->Br-(g)

K(s) + 1/2Br2------->KBr(s)

KBr(s)------->K+ + Br-

Answer 1

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.
