Unformatted text preview: de laney (asd644) Thermochemical equations Migiano (0001) 1 This print-out should have 15 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. Problem 2 - acetone has the chemical for- mula C3H6O 001 10.0 points In the manufacture of nitric acid by the oxi- dation of ammonia, the first product is nitric oxide. The nitric oxide is then oxidized to nitrogen dioxide: 2 NO(g) + O 2 (g)- 2 NO 2 (g) Calculate the standard reaction enthalpy for the reaction above (as written) using the following data: N 2 (g) + O 2 (g)- 2 NO(g) H = 180 . 5 kJ N 2 (g) + 2 O 2 (g)- 2 NO 2 (g) H = 66 . 4 kJ 1.- 128 . 2 kJ/mol rxn 2.- 520 . 2 kJ/mol rxn 3.- 114 . 1 kJ/mol rxn 4.- 975 . 0 kJ/mol rxn 5.- 100 . 3 kJ/mol rxn 6.- 252 . 4 kJ/mol rxn 7.- 690 . 72 kJ/mol rxn 002 10.0 points Calculate the enthalpy change that occurs when 1.00 kg of acetone condenses at its boil- ing point (329.4 K). The standard enthalpy of vaporization of acetone is 29.1 kJ mol 1 ....
