The cell in whiCHM the following reaction occurs `:`
`2Fe^(3+)(aq)+2I^(c-)(aq) rarr 2Fe^(2+)(aq)+I_(2)(s)` has
`E^(c-)``_(cell)=0.2136V` at `298K`. Calculate the standard Gibbs energy and the equilibrium constant of the cell reaction.

Text Solution

Verified by Experts

`DeltaG^(0)=-nFE^(@)`
`=-2 xx 96500 xx0.236J`
`=-45548J=-45.548kJ`
`"K=Antilog"[(nE^(@))/(0.059)]"= Antilog"(2xx0.236)/(0.059)=10^(8)`
