Gaseous N_2 O_4 dissociates into gaseous NO_2 according to the reaction N_2 O_4( g ) ⇌ 2 NO_2( g ) At 300 K and 1 atm pressure, the degree of…
Gaseous $\displaystyle \mathrm{N}_2 \mathrm{O}_4$ dissociates into gaseous $\displaystyle \mathrm{NO}_2$ according to the reaction
$$\mathrm{N}_2 \mathrm{O}_4(\mathrm{~g}) \rightleftharpoons 2 \mathrm{NO}_2(\mathrm{~g})
$$
At $\displaystyle 300$ K and $\displaystyle 1$ atm pressure, the degree of dissociation of $\displaystyle \mathrm{N}_2 \mathrm{O}_4$ is $\displaystyle 0.2$ . If one mole of $\displaystyle \mathrm{N}_2 \mathrm{O}_4$ gas is contained in a vessel, then the density of the equilibrium mixture is :
Official answer
(2)
3.$\displaystyle 11$ g/L
