MCQ
$Cu(s)|\,C{u^{ + 2}}(aq,{10^{ - 3}})\,|\,|\,A{g^ + }\,({10^{ - 5}}M)|\,Ag(s)$

if $E_{C{u^{ + 2}}/Cu}^o\, = \, + 0.34\,V$

$E_{A{g^ + }/Ag}^o\, = \, + 0.80\,V$

$E_{cell}$ will be

  • A
    $0.46\,V$
  • $0.46\,-\,\frac {RT}{2F}\,ln\,10^{+7}$
  • C
    $0.46\,+\,\frac {RT}{2F}\,ln\,10^7$
  • D
    $0.46\,-\,\frac {RT}{2F}\,ln\,10^{+2}$

Answer
