MCQ
Consider the cell given below

$Ag\left( s \right)/A{g^ \oplus }||C{u^{2 + }}/Cu\left( s \right)$

$A{g^ \oplus } + {e^ - } \to Ag\,;\,{E^o} = x$

$C{u^{2 + }} + 2{e^ - } \to Cu\,;\,{E^o} = y$

$E^o_{cell}$ is

  • A
    $x + 2y$
  • B
    $2x + y$
  • ✓
    $y -x$
  • D
    $y -2x$
✓

Answer

Correct option: C.
$y -x$
c
$\mathrm{E}_{\text {Cell }}^{0}=\left(\mathrm{E}_{\mathrm{red}}^{0}\right)_{\text {cathode }}-\left(\mathrm{E}_{\text {red }}^{0}\right)_{\text {Anode }}$

$E_{\text {Cell }}^{0}=\mathrm{y}-\mathrm{x}$
