Question

Stuck on this

Consider the following reaction:
PCI{(g) PC13(g)+ Cl2(g)
If 1.00×10-3 moles of PCI5, 0.302 moles of PC13, and 0.366 moles of Cl, are at equilibrium in a 17.0 L
container at 730 K, the value of the equilibrium constant, Kp. is

Expert Solution

Introduction

Equilibrium constants mainly get measured in concentration terms as well as pressure terms. The equilibrium constant evaluated in pressure terms is symbolized "K_p" whereas equilibrium constant evaluated in concentration terms is symbolized "K_c".

Solution

The given reaction is as follows,

The formula for the calculation of the equilibrium concentration/molarity is shown below.

Solution

Substitute the known values in the equation (II) to calculate the concentrations.

The concentration of PCl₅:

The concentration of PCl₃:

Solution

The concentration of Cl₂:

Substitute the known values in the equation (I).

Thus the value of equilibrium constant (K_c) is 6.513.
