The standard Gibbs energy change at 300K...

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)`

Text Solution

Verified by Experts

The correct Answer is:
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.
