If the E^(@) for a given reaction has a ...

If the `E^(@)` for a given reaction has a negative value, then which of the following gives the correct relationship for the of `DeltaG^(@)` and `k_(aq)`?

A

`DeltaG^(@) lt 0 , K_(eq) gt 1`

B

`DeltaG^(@) lt 0, K_(eq) lt 1`

C

`DeltaG^(@) gt 0, K_(eq) lt 1`

D

`DeltaG^(@) gt 0: K_(eq) gt 1`

Text Solution

Verified by Experts

The correct Answer is:
C

`DeltaG(@) =-nFE^(@)"cell" , E_("cell")^(@) =(-ve)`
So, `DeltaG^(@) = (+ve), DeltaG gt 0`
Also, `DeltaG^(@) =2.303 RT log K_(eq)`
`therefore K_(eq) lt 1`
