The cell in which the following reaction occurs
`2Fe^(3+)(aq)+2I^(-)(aq)to2Fe^(2+)(aq)+I_(2)(aq)+I_(2)(s)` has `E_(cell)^(0)=0.236V` at 298 K.
Calculate the stadard gibbs energy and the equilibrium constant of the cell reaction.

Text Solution

Verified by Experts

The correct Answer is:
`-45.548 kJ mol^(-1)`
`Delta_(r) G^(@) = - nFE_(cell)^(@)`
`Delta_(r) G^(@) = (2 mol) xx (96500 C mol^(-1)) xx (0.236 V)`
`= -45.548 kJ mol^(-1)`
