The standard Gibbs energy change at 300 ...

The standard Gibbs energy change at 300 K for the reaction `2A hArr B + C` is `2494.2 J.` 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 = 8.314 J//K//mol, e = 2.718]`

A

forward direction because `Q gt K_(C)`

B

reverse direction because `Q gt K_(C)`

C

forward direction because `Q lt K_(C)`

D

reverse direction because `Q lt K_(C)`

Text Solution

Verified by Experts

The correct Answer is:
B
Calculate `K_(eq) by DeltaG = -RTlnK_(eq)`
Since `Q > K_(eq) implies` reverse direction
