Problem- A researcher put 0.220 mol PCl3 and 0.132 mol Cl2 into a 4.70 L vessel at a given temperature to produce phosphorus pentachloride,
PCl5- PCl3(g) + Cl2(g) PCl5(g)
What will be the composition of this gaseous mixture at equilibrium? Kc = 25.6 at the temperature of this experiment.
[PCl3] = ?M
[Cl2] = ? M
[PCl5] = ?M
Express your answer to two significant figures and include the appropriate units.
