Compare the entropy changes for the following processes: a. One mole of zirconia is heated at one atmosphere from 300 to 1300 K. b. One mole of zirconia at 300 K is isothermally compressed from 1 atm to 100 kbars. (Use V = 22.0 (cc mol-1 ) and α = 10 × 10-6 K-1 ). c. One mole of oxygen is heated at one atmosphere from 300 to 1300 K. (Assume O2 is an ideal gas with CP = 7 / 2R). d. One mole of oxygen at 300 K is isothermally compressed from 1 atm to 100 kbars. What general qualitative conclusions do you draw from these calculations?

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 .
