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 "Kp" whereas equilibrium constant evaluated in concentration terms is symbolized "Kc".
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 (Kc) is 6.513.
