Consider the following equilibrium system: \[ \mathrm{PCl}_{5}(\mathrm{~g}) \rightleftharpoons \mathrm{PCl}_{3}(\mathrm{~g})+\mathrm{Cl}_{2}(\mathrm{~g}) \] A 10.00 L evacuated flask is filled with 0.4150 mol \( \mathrm{PCl}_{5}(\mathrm{~g}) \) at \( \mathbf{2 9 7 . 4} \mathrm{K} \). The temperature is then raised to 501.7 K , where the decomposition of \( \mathrm{PCl}_{5} \) gas takes place to an appreciable extent. When equilibrium is established, the total pressure in the flask is 2.433 atm.
