Given the equilibrium constant : K_C of the reaction : $Cu\left(s\right)+2A{g}^{+}\left(aq\right)\to C{u}^{2+}\left(aq\right)+2Ag\left(s\right)$ is 10 × 10¹⁵, calculate the $E_{cell}^0$ of this reaction at 298 K  

$\left[\text{2}\text{.303 }\frac{\text{RT}}{\text{F}}\text{ at}\text{298K = 0}\text{.059V}\right]$
