Question

The correct representation of Nernst equation is
A. `E_(M^(n+)//M)=E_(M^(n+)//M)^(o)+(0.0591)/(n)log(M^(n+))`
B. `E_(M^(n+)//M)=E_(M^(n+)//M)^(@)-(0.0591)/(n)log(M^(n+))`
C. `E_(M^(n+)//M)=E_(M^(n+)//M)^(o)+(n)/(0.0591)log(M^(n+))`
D. none of these

Answer 1

Correct Answer - A
`E=E^(o)-(RT)/(nF)ln(1)/([M^(n+)]),E=E^(o)+(RT)/(nF)ln[M^(n+)]`
`E=E^(o)+(2.303RT)/(nF)log[M^(n+)]`
Substituting the value of R,T (298K) and F we get
`E=E^(o)+(0.0591)/(n)log(M^(n+))`.
