Temprature of Potassium suproxide

[stamba]

Hello,
Does anyone know what are the temperatures of Potassium suproxide, potassium peroxide and potassium oxide on which they fall apart(oxigen goes away)?

How can I make KO2 in some syntesis?

[maverick280857]

Do you mean bond dissociation energies?

I think that the reaction,


K + O_{2} ---> KO_{2}


does take place (at high temp.). Correct me if I am wrong...


Cheers

I ment in the other way:

KO2 ----> K + O2

On what temperature it happens?
Thanks.
