As we have learned

Thermodynamics of the reaction -

\bigtriangleup G=0

- wherein

Reaction has achieved equilibrium at this point.There is no longer any free energy left to drive the reaction.

 

 When a reaction attains equilibrium the value of \Delta G  becomes equal to zero 

At equilibrium Q_c =K_c
