Calculate `E_(cell)^(@)` for the following reaction at `25^(@)C`. `A+B^(2+)(0.001 M) to A^(2+)(0.0001 M)+B` (Given. `E_(cell)=2.6805 V, 1 F=96500 C mol^(-1)`

Answer» According to Nernst equation
`E_(cell)=E_(cell)^(@)-(0.0591)/(n)"log"([Anode])/([Cathode])`
`E_(cell)^(@)=E_(cell)+(0.0591)/(2)"log"([0.0001])/([0.001])=2.6805+0.02955" log"10^(-1)"`
=2.6805-0.02955=2.6510 V
