The Kp for the reaction below is 1.49 × 108 at 100.0°C:CO(g) + Cl2(g) → COCl2(g)In an equilibrium mixture of the three gases, PCO = PCl2 = 2.22 × 10-4 atm. The partial pressure of the product, phosgene (COCl2), is atm.

The equilibrium partial pressure of phosgene is 7.34 atm

Explanation:

The given chemical equation follows:

The expression of for above equation follows:

We are given:

Equilibrium partial pressure of CO =

Equilibrium partial pressure of chlorine gas =

Putting values in above equation, we get:

Hence, the equilibrium partial pressure of phosgene is 7.34 atm

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
