Which of the following reactions is possible at the anode?

The $Cu^{+}$ ion is not stable in aqueous solution. For the disproportionation reaction,what is the $E^o$ value in $V$? (Given: $E^o_{Cu^{2+} | Cu^{+}} = 0.15 \, V$; $E^o_{Cu^{2+} | Cu} = 0.34 \, V$)

Write reactions for the followings :
$1.$ Anode reaction of dry cell.
$2.$ Reduction reaction of dry cell.

Given the data at $25\, ^oC$:
$Ag + I^{-} \rightarrow AgI + e^-$,$E^o = 0.152\, V$
$Ag \rightarrow Ag^{+} + e^-$,$E^o = -0.800\, V$
What is the value of $\log K_{sp}$ for $AgI$? $(2.303\, RT/F = 0.059\, V)$
