    If \[{{K}_{c}}\] for the reaction \[C{{u}^{2+}}(aq)+S{{n}^{2+}}(aq)\xrightarrow{{}}\,S{{n}^{4+}}(aq)+Cu(s)\] at \[25{}^\circ C\] is represented as \[2.6\times {{10}^{y}}\] then find the value of y. (Given: \[E{{{}^\circ }_{C{{u}^{2+}}\left| Cu \right.}}=0.34V;\,\,E_{S{{n}^{4+}}\left| S{{n}^{2+}} \right.}^{{}^\circ }=0.15V\])
