Answer :

• In the viewpoint of thermodynamics, Equilibrium can be explained by the following mathematical equation :

**∆G =** **∆****G**^{⊖}**+ RTlnQ** which comes down to

∆G = ∆G^{⊖} + RTlnK and then to

**∆****G**^{⊖}**= - RTlnK** (as at Equilibrium ∆G is zero and Kc is = Q

Now, for the reaction A ⇋ B, at the stage of half completion of the reaction, the concentration of [A] will be equal to [B] i.e. **[A] = [B]**

Hence, the value of K becomes equal to = =1

The value of **ln1 = 0** ,

Hence ∆G^{⊖} = - RTlnK = 0

therefore (i) ∆G^{⊖} = 0 is the correct answer.
