Equilibrium condition in the course of a reversible chemical reaction is in which no net change in the amounts of reactants and products occurs.
At cquilibrium, the reaction is half completed.
[A]=[B]
Thus,

[B]

[A]

=1
According to standard free Gibbs energy,
ΔG°=−RT‌ln‌K
ΔG°=−RT‌ln(l)
[ΔG°=0]
Hence, at equilibrium condition, the reaction is half-completed i.e., A⇌B.
