The two most abundant atmospheric gases react to a tiny

Chapter 17, Problem 80P

(choose chapter or problem)

The two most abundant atmospheric gases react to a tiny extent at 298 K in the presence of a catalyst:

                \(\mathrm{N}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{NO}(\mathrm{g}) \quad K_{p}=4.35 \times 10^{-31}\)

(a) What are the equilibrium pressures of the three components when the atmospheric partial pressures of \(\mathrm{O}_{2}\)  (0.210 atm) and of \(\mathrm{N}_{2}\) (0.780 atm) are put into an evacuated 1.00-L flask at 298 K with catalyst?

(b) What is \(P_{\text {total}}\) in the container?

(c) Find \(\mathrm{K}_{c}\) for this reaction at 298 K.
