E°cell=E°cathode-E°anode It will remain unchanged.

Q. In a cell reaction, $C u_{(s)} + 2 A g_{(a q)}^{+} \to C u_{(a q)}^{2 +} + 2 A g_{(s)} E_{ce ll}^{\circ} = + 0.46 V$ If the concentration of $C u^{2 +}$ ions is doubled then $E_{ce ll}^{\circ}$ will be

doubled

halved

increased by four times

unchanged

$E_{ce ll}^{\circ} = E_{c a t h o d e}^{\circ} - E_{an o d e}^{\circ}$
It will remain unchanged.
