Consider the cell at 25\(^\circ\)C
Zn | Zn2+ (aq), (1M) || Fe3+ (aq), Fe2+ (aq) | Pt(s)
The fraction of total iron present as Fe3+ ion at the cell potential of 1.500 V is x \(\times\) 10\(-\)2. The value of x is ______________. (Nearest integer)
(Given : \(E_{F{e^{3 + }}/F{e^{2 + }}}^0 = 0.77V\), \(E_{Z{n^{2 + }}/Zn}^0 = - 0.76V\))
