The physical properties of matter produce many cause and effect relationships. Which effort is produced by the close packing of

stepan [7]

Answer:

Explanation:

We know quite well that there are three states of matter. Solid,liquid and gaseous states.

While the gaseous states gives the highest freedom of movement, the solid state gives the least freedom of movement. Molecules and atoms of a solid are so tightly packed.

This makes them very dense as they are held together by strong intermolecular forces of attraction. These strong forces prevents the movement of the particles.

As these particles are strongly attracted towards each other, they tend to be incompressible.

DochEvi [55]

Answer:

Explanation:

PCl₅ ⇄ PCl₃ + Cl₂

1 mole 1 mole 1 mole

molecular weight of PCl₅ = 208.5

molecular weight of PCl₃ = 137.5

molecular weight of Cl₂ = 71

moles of PCl₅ = .0185

moles of PCl₃ = .0924

moles of Cl₂ = .1873

Total moles = .2982 moles

mole fraction of PCl₅ = .062

mole fraction of PCl₃ = .31

mole fraction of Cl₂ = .628

If total pressure be P

partial pressure of PCl₅ = .062 P

partial pressure of PCl₃ = .31 P

partial pressure of Cl₂ = .628 P

Kp = .31 P x .628 P / .062 P

= 3.14 P

To calculate Total pressure P

PV = nRT

P x 4 x 10⁻³ = .2982 x 8.31 x 600

P = 371.7 x 10³

= 3.717 x 10⁵ Pa

Kp = 3.14 P = 3.14 x 3.717 x 10⁵ Pa

= 11.67 x 10⁵ Pa

Kp = Kc x $( RT )^{\triangle n}$

$\triangle n$ = 1

11.67 x 10⁵ = Kc x $( 8.31\times 600 )^{1}$

Kc = 234
