Nitric oxide, oxygen, and nitrogen react by the following equation.
2 NO(g) N2(g) + O2(g)Kc = 2.3 1030 at 298 K
(a) In the atmosphere, PO2 = 0.209 atm and PN2 = 0.781 atm. What is the equilibrium partial pressure of NO in the air we breathe? [Hint: You need the Kp to find the partial pressure.]
(b) If Qp = 1.2 1020 and PO2 = 0.318 and PN2 0.812, what is the partial pressure of NO?
