Consider the cell
Pt, H$$_2$$(g, 1 atm) | H$$^+$$ aq, 1M | Fe$$^{3+}$$ aq, Fe$$^{2+}$$ aq | Pt s
When the potential of the cell is 0.712 V at 298 K, the ratio Fe$$^{2+}$$/Fe$$^{3+}$$ is ______ (Nearest integer)
Given: Fe$$^{3+}$$ + e$$^-$$ = Fe$$^{2+}$$, E° Fe$$^{3+}$$, Fe$$^{2+}$$ Pt = 0.771, $$\frac{2.303RT}{F} = 0.06$$ V
