Answer:
The equilibrium constant of the given reaction is 0.01351.
Explanation:

The equilibrium constant of the reaction = 
...[1]

The equilibrium constant of the reaction = 
..[2]
![[Cl^-]=\frac{K_4\times [AgCl]}{[Ag^+]}](https://tex.z-dn.net/?f=%5BCl%5E-%5D%3D%5Cfrac%7BK_4%5Ctimes%20%5BAgCl%5D%7D%7B%5BAg%5E%2B%5D%7D)

The expression of equilibrium constant of the creation is ;
![K=\frac{[AgCl]^2[Pb^{2}]}{[PbCl_2]][Ag^+]^2}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BAgCl%5D%5E2%5BPb%5E%7B2%7D%5D%7D%7B%5BPbCl_2%5D%5D%5BAg%5E%2B%5D%5E2%7D)
Dividing [1] by [2]
![\frac{K_3}{K_4}=\frac{\frac{[Pb^{2+}][Cl^-]^2}{[PbCl_2]}}{\frac{[Ag^+][Cl^-]}{[AgCl]}}](https://tex.z-dn.net/?f=%5Cfrac%7BK_3%7D%7BK_4%7D%3D%5Cfrac%7B%5Cfrac%7B%5BPb%5E%7B2%2B%7D%5D%5BCl%5E-%5D%5E2%7D%7B%5BPbCl_2%5D%7D%7D%7B%5Cfrac%7B%5BAg%5E%2B%5D%5BCl%5E-%5D%7D%7B%5BAgCl%5D%7D%7D)
![\frac{K_3}{K_4}=\frac{[Pb^{2+}][Cl^-][AgCl]}{[PbCl_2][Ag^+]}](https://tex.z-dn.net/?f=%5Cfrac%7BK_3%7D%7BK_4%7D%3D%5Cfrac%7B%5BPb%5E%7B2%2B%7D%5D%5BCl%5E-%5D%5BAgCl%5D%7D%7B%5BPbCl_2%5D%5BAg%5E%2B%5D%7D)
Substituting the value of
from [2] :
![\frac{K_3}{K_4}=\frac{[Pb^{2+}][AgCl]}{[PbCl_2][Ag^+]}\times \frac{K_4\times [AgCl]}{[Ag^+]}](https://tex.z-dn.net/?f=%5Cfrac%7BK_3%7D%7BK_4%7D%3D%5Cfrac%7B%5BPb%5E%7B2%2B%7D%5D%5BAgCl%5D%7D%7B%5BPbCl_2%5D%5BAg%5E%2B%5D%7D%5Ctimes%20%5Cfrac%7BK_4%5Ctimes%20%5BAgCl%5D%7D%7B%5BAg%5E%2B%5D%7D)



The equilibrium constant of the given reaction is 0.01351.
The answer would be C. Movement of crustal plates.
