For a spontaneous reaction, `DeltaG`, equilibrium constant K and `E_("cell")^(@)` will be respectively

A

-ve, gt1,+ve

B

+v, gt1, -ve

C

-ve, lt1, -ve

D

-ve, gt1,-ve

Text Solution

Verified by Experts

For sponteneous reaction
`G=-Ve ` so,`E_(cell)^(0)=+ve` as `DeltaG=-nFE_(cell)^(0) and DeltaG=-RT 1n K`
`DeltaG=-RTxx2.303 logK ` As `DeltaG-ve` so,`K gt1`
