  how  stability   of  peroxide  and  superoxide  increases  as  the  size  of  alkali  metals  increases??

As the size of alkali metal ion increases the stability of peroxides and super oxides increases. This is due to the stabilization of larger anions by larger cations.
As we move from Li+ to Cs<...
