Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas: pcl₃(g)+cl₂(g)⇌pcl₅(g). a 7.5-l gas vessel is charged with a mixture of pcl₃(g) and cl₂(g), which is allowed to equilibrate at 450 k. at equilibrium the partial pressures of the three gases are ppcl₃ = 0.129 atm, pcl₂ = 0.156 atm, and ppcl₅ = 1.40 atm. what is the value of kp at this temperature? express your answer using three significant figures.

Explanation:

As the given reaction is as follows.

Hence, expression for will be as follows.

Now, putting the given values into the above formula as follows.

                    =

                    = 69.6

Therefore, we can conclude that the value of is 69.6.    

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
