Q1

For the disproportionation reaction \(2 \mathrm{Cu}^{+}(\mathrm{aq}) \rightleftharpoons \mathrm{Cu}(\mathrm{s})+\mathrm{Cu}^{2+}(\mathrm{aq})\) at \(298 \mathrm{~K}\), In \(\mathrm{K}\) (where \(\mathrm{K}\) is the equilibrium constant) is _____\(\times 10^{-1}\).

Given :

\(\left({\mathrm{E}}_{{\mathrm{Cu}}^{2+}/{\mathrm{Cu}}^{+}}^{\mathrm{o}}=0.16\mathrm{V},{\mathrm{E}}_{{\mathrm{Cu}}^{2+}/\mathrm{Cu}}^{\mathrm{o}}=0.52\mathrm{V},\frac{\mathrm{RT}}{\mathrm{F}}=0.025\right)\)
