Question
Problems 33 and 34 both concern the dissociation of phosphorus pentachloride into chlorine and phosphorus trichloride, which has Kp = 0.015 at 450 K.
PCl5(g) ⇌ PCl3(g) + Cl2(g) , Kp = 0.015
A closed container at 450 K initially contains only PCl5(g) and PCl3(g), each with a partial pressure of 2.7 bar. After the system reaches equilibrium, what is the partial pressure of Cl2(g)?
A.✓ Correct
0.015 bar
B.
0.12 bar
C.
0.20 bar
D.
2.7 bar
