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^(@)gt0,k_(eq)lt1`

B

`DeltaG^(@)gt0,k_(eq)gt1`

C

`DeltaG^(@)lt0,k_(eq)gt1`

D

`DeltaG^(@)lt0,k_(eq)lt1`.

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaG^(@)=-nFE_("cell")^(@)`
and `DeltaG=RT "In" k_(eq)`
From (i) `E_("cell")^(@)` is negative, `DeltaG^(@)` can be postive only if `k_(eq)lt1`
