Question

Consider the following system at equilibrium at 25°C:PCl₃(g) + Cl₂(g)

Consider the following system at equilibrium at 25°C:PCl<sub>3</sub>(g) + Cl<sub>2</sub>(g) PCl<sub>5</sub>(g) for which ΔH° = -92.5 kJ at 25°C. -When some Cl<sub>2</sub>(g) is added at constant volume and temperature, the ratio of the partial pressure of PCl<sub>5</sub> to the partial pressure of PCl<sub>3</sub> will A) stay the same. B) It is impossible to tell without more information. C) increase. D) decrease.

PCl₅(g)
for which ΔH° = -92.5 kJ at 25°C.
-When some Cl₂(g) is added at constant volume and temperature, the ratio of the partial pressure of PCl₅ to the partial pressure of PCl₃ will

Quizplus · Accepted Answer

The addition of Cl2(g) will shift the equilibrium to the right, increasing the partial pressure of PCl5 and decreasing the partial pressure of PCl3.
