Gases from the air..........

Regardint the isolation of noble gases from atomosphric air by Ramsay - Rayleigh's second method four equations are given below I) N_2 + O_2 + 2NO II) 2NO + O_2 to 2NO_2 III) 2NO_2 + 2NaOH to NaNO_2 + NaNO_3 + H_2O IV) CaC_2 + N_2 overset(Delta)to CaCN_2+ C In this method, the reactions truely involved are
