Question
A chemist studying reactions of phosphorus halides. The chemist determined
concentrations of every substance in the reaction at a certain point as follows:
10.1 M of PCI5 with 0.18 M of Cl2 and 0.18 M of PC13 at 250 °C.
PCI5(g)
PCI3(g) + Cl2(g) K. = 4.2 × 10²
In which direction the reaction proceeds to reach equilibrium?
