Question

What is the Nernst Equation?

Answer 1

$E_{cell}=E_{cell}^{\circ }-\frac{RT}{nF}lnQ$
where
$E_{cell}$ = cell potential at non-standard state conditions;
$E_{cell}^{\circ }$ = cell potential at standard state
$R$ = the universal gas constant $(8.314J.K^{-1}mo{l}^{-1}=0.314V.C.K^{-1}mo{l}^{-1})$
$T$ = Kelvin temperature;
$F$ = Faraday's constant $\left(69458C/mol{e}^{-}\right)$;
$n$ = number of moles of electrons transferred in the balanced equation for the cell reaction;
$Q$ = reaction quotient for the reaction $aA+bB\rightleftharpoons cC+dD$
