Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction

0.204.

Explanation:

CO(g) + Cl₂(g) ⇌ COCl₂(g),

Kp = (P of COCl₂)/(P of CO)(P of Cl₂)

P of COCl₂ = 0.22 atm, P of CO = 0.83 atm, P of Cl₂ = 1.3 atm.

∴ Kp = (P of COCl₂)/(P of CO)(P of Cl₂) = (0.22 atm)/(0.83 atm)(1.3 atm) = 0.204.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
