$P =\left[ FeF _6\right]^{3-}, Q =\left[ V \left( H _2 O \right)_6\right]^{2+} \text { and } R =\left[ Fe \left( H _2 O \right)_6\right]^{2+} \text {. }$
The correct order of the complex ions, according to their spin-only magnetic moment values (in $B.M.$) is
${E^o}_{\left( {{I_2}/{I^ - }} \right)},{E^ \circ }_{\left( {Br^-/B{r_2}} \right)}$ and ${E^ o }_{\left( {{Fe}/{Fe^{2+} }} \right)}$
are respectively $+ 0.54\ V$, $-1.09\ V$ and $0.44\ V$. On the basis of above data which of the following process is non-spontaneous
