⦁ Nitrogen reacts with hydrogen according to the following reaction: N2 (g) + 3H2 (g) 2NH3 (g)

If the initial partial pressures of N2 and H2 are 1.2 atm and 0.8 atm, respectively, what is total pressure at the end of the reaction in atm?
Assume the reactions occurs in a 1.0L flask at 298K
R = 0.08206 L*atm/mol*K

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 .
