Chemistry - Chemical Equilibrium Question with Solution | TestHub

At 298 K , the equilibrium between ${\mathrm{N}}_2{\mathrm{O}}_4$ and ${\mathrm{NO}}_2$ is represented as: ${\mathrm{N}}_2{\mathrm{O}}_4(\mathrm{g})\rightleftharpoons 2{\mathrm{NO}}_2(\mathrm{g})$. If the total pressure of the equilibrium mixture is P and the degree of dissociation of ${\mathrm{N}}_2{\mathrm{O}}_4(\mathrm{g})$ at 298 K is $x$, the partial pressure of ${\mathrm{NO}}_2(\mathrm{g})$ under these conditions is
