Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride according to the following equilibrium: 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 = 0.121 atm , pcl2 = 0.157 atm , and ppcl5 = 1.90 atm .

In what environment would mineral formation caused by high pressures and high temperatures most likely occur?

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
