Which of the following options will be correct for the stage of half completion of the reaction : `AhArrB` ?

Options

A. `DeltaG^(Theta)=0`
B. `DeltaG^(Theta) gt0`
C. `DeltaG^(Theta) lt0`
D. `DeltaG^(Theta) =-RT ln K`

Answer

A

Explanation

As we know that `DeltaG^(Theta) =-RT ` ln K
At the stage of half completion of the reaction, `A hArr B ,[A] =[B]`
Therefore, K = 1
Thus, `DeltaG^(Theta) =0`
