An 8.25 gram sample of PCl5 is placed in an evacuated 2.00 L flask and is completely vaporized at 400 K. a. Calculate the pressure in the flask if no chemical reaction were to occur. b. However, at 400 K, the PCl5 is partially dissociated according to the following equation. PC15<->PCl3 + Cl₂ C. The observed pressure is found to be 0.900 atm. Calculate the partial pressures of PC13 and PCl5 in the flask. Write the Kp expression and calculate Kp for the reaction.
