Select the reaction type for the above reactions:

The crystal field stabilization energy (CFSE) for $[{\text{CoCl}}_6{]}^{4-}$ is $18000{\text{cm}}^{-1}$. The CFSE for $[{\text{CoCl}}_4{]}^{2-}$ will be:

The standard electrode potential ($E^{\circ }$) values of ${\text{Al}}^{3+}/\text{Al}$, ${\text{Ag}}^{+}/\text{Ag}$, ${\text{K}}^{+}/\text{K}$, and ${\text{Cr}}^{3+}/\text{Cr}$ are $-1.66\text{V}$, $0.80\text{V}$, $-2.93\text{V}$, and $-0.79\text{V}$ respectively. The correct decreasing order of the reducing power of the metal is:

The correct order of ionic radii is:
