The standard Gibbs energy change at `300K` for the reaction `2AhArrB+C` is 2494. `2J`. At a given time, the composition of the reaction mixture is `[A]=1/2, [B]=2` and `[C]=1/2`. The reaction proceeds in the `(R=8.314JK//"mol"e=2.718)`A. forward direction because `QgtK_(C)`B. reverse direction because `QgtK_(C)`C. forward direction because `QltK_(C)`D. reverse direction because `QltK_(C)`

Answer» Correct Answer - B
`DeltaG=DeltaG^(@)+RT "in" Q=2494.2+8.314xx300 "in" 4=` positive
DeltaG=RTln(Q)/(K)`
Since, `DeltaG` is positive so, `QgtK`, so reaction shifts in reverse direction.
