A solution containing \[1M\text{ }XS{{O}_{4}}\] (aq) and \[1M\,YS{{O}_{4}}\] (aq) is electrolysed. If cone. of \[{{X}^{2+}}\] is \[{{10}^{-z}}M\] when deposition of \[{{Y}^{2+}}\]and \[{{X}^{2+}}\] starts simultaneously, calculate the value of Z. Given: \[\frac{2.\,303RT}{F}=0.06\] \[E{{{}^\circ }_{{{X}^{2+}}/X}}=-\,0.12V;\,\,E{{{}^\circ }_{{{Y}^{2+}}/Y}}=-\,0.24\,V\]
