In a study of the formation of NOx air pollution, a chamber heated to 2200°C was filled with air (0.790 atm N₂, 0.210 atm O₂). What are the equilibrium partial pressures of N₂, O₂, and NO if Kp = 0.0520 for the following reaction:

N₂(g) + O₂(g) ⇌ 2NO(g)

a. 0.656 atm, 0.174 atm, 0.0520 atm
b. 0.0520 atm, 0.139 atm, 0.139 atm
c. 0.104 atm, 0.0520 atm, 0.0520 atm
d. 0.026 atm, 0.026 atm, 0.104 atm
