The magnitude of the change in oxidising power of the \\( \mathrm{MnO_4^{-}/Mn^{2+}} \\) couple is \\( x \times 10^{-4} \, \text{V} \\), if the \\( \mathrm{H^+} \\) concentration is decreased from \\( 1 \, \text{M} \\) to \\( 10^{-4} \, \text{M} \\) at \\( 25^\circ \text{C} \\) (Assume concentration of \\( \mathrm{MnO_4^{-}} \\) and \\( \mathrm{Mn^{2+}} \\) to be same on change in \\( \mathrm{H^+} \\) concentration). The value of \\( x \\) is _____ (Rounded off to the nearest integer)
[Given: \\( \frac{2.303RT}{F} = 0.059 \\)]
