Problem 5.5.32

Statement

5.5.32. At room temperature, nitrogen tetroxide partially dissociates, turning into nitrogen dioxide: $N_2O_4 \rightleftharpoons 2NO_2$. $0.92 \,g$ of liquid $N_2O_4$ at $0 \,^{\circ}C$ is introduced into an evacuated vessel with a capacity of $250 \,cm^3$. When the temperature in the vessel rises to $27 \,^{\circ}C$, the liquid evaporates completely, and the pressure becomes equal to $128 \,kPa$. Determine the fraction of nitrogen tetroxide that dissociated.
