Given the two reactions PbCl2(aq)⇌Pb2+(aq)+2Cl−(aq), K3 = 1.85×10−10, and AgCl(aq)⇌Ag+(aq)+Cl−(aq), K4 = 1.17×10−4, what is the equilibrium constant Kfinal for the following reaction? PbCl2(aq)+2Ag+(aq)⇌2AgCl(aq)+Pb2+(a q)

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]

The expression of equilibrium constant of the creation is ;

Dividing [1] by [2]

Substituting the value of from [2] :

The equilibrium constant of the given reaction is 0.01351.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
