Two equilibria exist simultaneously in a vessel at 25∘CNO(g)+NO2(g)K

1.	Two equilibria exist simultaneously in a vessel at 25∘CNO(g)+NO2(g)KP1=0.4 atm−1⇌N2O3(g) 2NO2(g)KP2=8 atm−1⇌N2O4(g)If initially only NO and NO2 are present in a 3:5 mole ratio and the final pressure at equilibrium of NO2 at 0.5 atm, then calculate total pressure (in atm) at equilibrium.
Answer» Two equilibria exist simultaneously in a vessel at $25^{\circ} C$ $\begin{matrix} N O (g) & + & N O_{2} (g) & K_{P 1} = 0.4 a t m^{- 1} ⇌ & N_{2} O_{3} (g) \end{matrix}$ $\begin{matrix} 2 N O_{2} (g) & K_{P 2} = 8 a t m^{- 1} ⇌ & N_{2} O_{4} (g) \end{matrix}$ If initially only $N O$ and $N O_{2}$ are present in a 3:5 mole ratio and the final pressure at equilibrium of $N O_{2}$ at 0.5 atm, then calculate total pressure (in atm) at equilibrium.
