1. The equilibrium constant for the reaction
below is 0.18 at 25oC.
PCl3(g) + Cl2(g)
PCl5(g)
The following concentrations were measured
from the reaction vessel:
[PCl3(g)] = 0.0420
[Cl2(g)] = 0.0240
[PCl5(g)] = 0.00500
a. Is this system in equilibrium?
Explain
b. If not, in which direction will the
system shift?
a) =
駒5
駒3 駒2
=
0.005
0.042 0.024
= 4.96
Since > 情 then the reaction is not at
equilibrium.
