At 2200°C, K = 0.050 for the following reaction.
N2(g) + O2(g) 2 NO(g)

What is the partial pressure of NO in equilibrium with N2 and O2 that were placed in a flask at initial pressures of 0.81 atm and 0.20 atm, respectively

...........N2 + O2 ==> 2NO
initial.0.81.....0.20....0
change...-p.....-p.....+2p
equi.....0.81-p..0.20-p..2p

Substitute into Kp expression and solve for x, then evaluate concns elements/compounds at equil conditions.
