Chemistry

1. There are three parts to this question. 2 moles of gaseousPCl5, are heated at 502 K till equilibrium is reached at a totalpressure of 1 atm. (a) Calculate the composition at equilibrium andalso the percentage of PCl5 decomposed at 502 K. (KoP = 0.46). (b)If the pressure of the system given in part (a) is raised to 10 atmat the same temperature of 502 K, calculate the percent of PCl5decomposed. Compare your results in part (a) and part (b) andexplain the significance of increasing the pressure of the systemfor the decomposition of PCl5. (c) If the system already contains 1mole of Cl2 in addition to the 2 moles of PCl5, calculate thepercent of PCl5 decomposed. The equilibrium pressure under thiscondition is 1 atm.
