By comparing the value of ionization energies the thermodynamic stability of transition metal compound can be compared. Ionization value shows that Ni(I I) compound are more stable then Pt(.II.) compound while Pt(.IV.) compound are relatively more stable than Ni(.IV.) .

Q. Which of the following pairs of compounds are more stable?

$K_{2} [NiCl_{6}], [Pt (CN)_{4}]^{2 -}$

$N i C l_{4}, PtC l_{4}$

$[Ni (CN)_{4}]^{2 -}, K_{2} [PtCl_{6}]$

$PtC l_{2}, N i C l_{2}$

By comparing the value of ionization energies the thermodynamic stability of transition metal compound can be compared. Ionization value shows that $N i (II)$ compound are more stable then $Pt (II)$ compound while $Pt (I V)$ compound are relatively more stable than $N i (I V)$ .
