Phosphorous trichloride and phosphorous pentachloride equilibrate in the presence of molecular chlorine according to the reaction:
pcl3 (g) + cl2 (g) → pcl5 (g)
an equilibrium mixture at 450 k contains ppcl3 = 0.124 atm, pcl2 = 0.157 atm, and ppcl5 = 1.30 atm.

what is the value of kp at this temperature?

Kp = 67

Explanation:

The reaction is given as:

PCl3 (g) + Cl2 (g) → PCl5 (g)

Now, the Kp expression at equilibrium for this reaction is written as:

Notes:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
