The equilibrium constant Kc for the reaction

equals 4.1 at 300oC.
a. A sample of 35.8 g of PCl5 is placed in a 5.0-L reaction vessel and heated to 300oC. What are the equilibrium concentrations of all of the species?
b. What fraction of PCl5 has decomposed?
c. If 35.8 g of PCl5 were placed in a 1.0-L vessel, what qualitative effect would this have on the fraction of PCl5 that has decomposed (give a qualitative answer only; do not do the calculation)? Why?
