KO_(2) _ H_(2)O to

For the reaction 2H_(2) + 2NO rarr N_(2) + 2H_(2)O , the following mechanism has been suggested : 2NO ? N_(2)O_(2) equilibrium constant K_(1) (fast) N_(2)O_(2) +H_(2) overset(k_(2)) rarr N_(2)O +H_(2)O (slow) N_(2) O +H_(2) overset(k_(3)) rarr N_(2)+H_(2)O (fast) Establish the rate law for given reaction.

Which one is not observed in the reaction? KO_(2)+H_(2)O+CO_(2)rarrKHCO_(3)+O_(2)

The reaction H_(2)O_(2)to H_2O +[O] is a

In a reaction, H_(2)O +C rarr CO +H_(2)

For the reaction 2Fe^(2+) + H_(2)O_(2) rarr 2Fe^(3+) + 2overset(ɵ)(OH) , the rate of formation of Fe^(3+) is given by Rate = k[Fe^(2+)][H_(2)O_(2)] . Suggest a mechanism for the reaction and and indicate a probable rate-determining step.

Potassium superoxide KO_(2) , is utillised in closed system breathing apparatus. Exhaled air contains CO_(2) and H_(2)O , both of which are removed and the removal of water generates oxygen for breathing by the reaction 4KO_(2(s))+2H_(2)O_((l))rarr 3O_(2(g))+ 4KOH_((s)) The potassium hydroxide removes CO_(2) from the apparatus by the reaction: KOH_((s))+CO_(2(g))rarr KHCO_(3(s)) (a) What mass of KO_(2) generates 20 gm of oxygen? (b) What mass of CO_(2) can br removed from the apparatus by CO_(2) can be removed from the apparatus by 100gm of KO_(2) ?
