Question

At $25^{\circ} C$ , the standard oxidation potentials of $Z n and A g$ in water are:
$Z n (s) \to Z n^{+ 2} (aq) + 2 e^{-}, E^{0} = 0.76 V$
and $A g (s) \to A g^{+} (aq) + e^{-}, E^{0} = - 0.80 V$ .
Which of the following reaction actually takes place?

Z n^{2 +} (aq) + 2 A g (s) \to 2 A g^{+} (aq) + Z n (s)
