If 'A' is the reactant and 'P' is the product, which one of the following is the correct form of Nernst equation?

Options

A. `([A])/([P])=exp((RT)/(nF)(E-E^(@)))`
B. `([A])/([P])=exp((nF)/(RT)(E-E^(@)))`
C. `([A])/([P])=exp(-(nF)/(RT)(E-E^(@)))`
D. `E-E^(@)-(RT)/(nF)In([A])/([P])`

Answer

B

Explanation

According to Nernst equation :
` E = E^(@) - (RT)/(fR) " In"(["Product"])/([Reactant"])`
or , ` E = E^(@) - (RT)/(nF) "In" ([P])/([A])`
or , ` E - E^(@) = - (RT)/(nF) " In" [P/A]`
or , ` [A/P] = exp^([(nF)/(RT) (E - E^(@))]`
Hence , option (b) is the correct answer .
