Problem- Phosphorous trichloride, PCl3, is a very corrosive and toxic compound that can be lethal in just a few minutes. It is used as a precursor to make a less toxic and useful reagent in the synthesis of organic compounds, PCl5. The reaction occurs when PCl3 is heated to a suffiently high temperature with Cl2.
PCl3(g) + Cl2(g) -----> PCl5 (g) Kp= 24.2 at 250°C
A reckless lab worker stores 0.050 moles of PCl5 in a 1.00-L flask in a cabinet near a furnace where the temperature is 150°C.
1) What is the partial pressure of each of the compounds in the system when equilibrium as been achieved?
