Question
A sample of pure NO2 gas heated to 1000 K decomposes : 2NO2(g) ⇋ 2NO(g) + O2(g). The equilibrium constant KP is 100 atm. Analysis shows that the partial pressure of O2 is 0.25 atm. at equilibrium. The partial pressure of NO2 at equilibrium is:
Options
A.0.03
B.0.25
C.0.025
D.0.04
Solution
2NO2 ⇋ 2NO(g) + O2(g)
Kp =
given PO2 = 0.25 ; PNO2 = 0.25
100 =
(PNO2)2 =
PNO2 = 0.025
Kp =
given PO2 = 0.25 ; PNO2 = 0.25
100 =
(PNO2)2 =
PNO2 = 0.025
