Question

$E_1$, $E_2$, and $E_3$ are the emfs of the following three galvanic cells respectively:
(i) Zn(s) | $Zn^{2+}$ (0.1 M) || $Cu^{2+}$ (1 M) | Cu(s)
(ii) Zn(s) | $Zn^{2+}$ (1 M) || $Cu^{2+}$ (1 M) | Cu(s)
(iii) Zn(s) | $Zn^{2+}$ (1 M) || $Cu^{2+}$ (0.1 M) | Cu(s)
Which one of the following is true?

$E_2 > E_1 > E_3$

$E_1 > E_2 > E_3$

$E_3 > E_1 > E_2$

$E_3 > E_2 > E_1$
