Problem
NO and NO2 are mixed in a container at constant volume to attain for the equilibrium :
2NO2⇌N2O4NO+NO2⇌N2O3
If partial pressures of PNO2′ and PN2O4′ are 0.5 and 1.7 atm respectively and equilibrium pressure is 5.05 atm, the initial pressure (atm) of NO would be :
(1) 2.20
(2) 2.85
(3) 3.20
(4) 3.85
