A 6.19 gram sample of PCl5 is placed in an evacuated 2.00 liter flask and is completely vaporized at 252*C.?

a. Calculate the pressure if no chemical reaction were to occur.

b. Actually at 252*C the PCl5 is partially dissociated according to the following equation:

PCl5 (g) -> PCl3 (g) + Cl2 (g)

The observed pressure is found to be 1.00 atmosphere. In view of this observation, calculate the partial pressure of PCl5 and PCl3 in the flas at 252*C.
