Question

Relationship between equilibrium constant of the reaction and standard electrode potential of electrochemical cell in which that reaction takes place is ____________.

Options

  • `"E"_"cell"^0 = (2.303  "RT")/("nF") log "K"_"c"`

  • `"E"_"cell"^0 = (2.303  "RT")/("F") log "K"_"c"`

  • `"E"_"cell"^0 = (2.03  "RT")/("nF") log "K"_"c"`

  • `"E"_"cell"^0 = (2.230  "RT")/("nF") log "K"_"c"`

Solution

Relationship between equilibrium constant of the reaction and standard electrode potential of electrochemical cell in which that reaction takes place is `underline("E"_"cell"^0 = (2.303  "RT")/("nF") log "K"_"c")`.

Explanation:

∆G0 = − 2.303 RT log Kc; ∆G0 = `-"nFE"_"cell"^0`

Equating, `"E"_"cell"^0 = (2.303  "RT")/"nF" log "K"_"c"`
