Consider the following equilibrium system: PCl5(g) -->PCl3(g) + Cl2(g) A 10.00 L evacuated flask is filled with 0.4334 mol PCl5(g) at 297.3 K. The temperature is then raised to 510.0 K, where the decomposition of PCl5 gas takes place to an appreciable extent. When equilibrium is established, the total pressure in the flask is 2.665 atm. What is the value of the equilbrium constant in terms of concentrations, Kc, at 510.0 K?
