Under a particular reaction condition if the value of the reaction-quotient (Q) is 1, then find out the change in the value of free energy `(DeltaG)`.

Explanation

We know, `DeltaG=RTln((Q)/(K))`
If Q=1, then `DeltaG=RTln((l)/(K))=-RTlnK=DeltaG^@`
Thus, the change in free energy `(DeltaG)` of the reaction is equal to the standard free energy change `(DeltaG^(0))`.
