Cheung, Anthony – Homework 11 – Due: Nov 26 2006, midnight – Inst: McCord 1 This print-out should have 30 questions. Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. The due time is Central time. Remember our old book (and others) reFer to internal energy with an E, not U. So assume that Δ E = Δ U For those older questions. 001 (part 1 oF 1) 10 points In the manuFacture oF nitric acid by the oxi- dation oF ammonia, the frst 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) Δ H = 180 . 5 kJ N 2 (g) + 2 O 2 (g) -→ 2 NO 2 (g) Δ H = 66 . 4 kJ 1. - 252 . 4 kJ/mol rxn 2. - 114 . 1 kJ/mol rxn 3. - 128 . 2 kJ/mol rxn 4. - 520 . 2 kJ/mol rxn 5. - 100 . 3 kJ/mol rxn 6. - 690 . 72 kJ/mol rxn 7. - 975 . 0 kJ/mol rxn 002 (part 1 oF 1) 10 points Calculate the reaction enthalpy For the Forma- tion 2 Al(s) + 3 Cl 2 (g) -→ 2 AlCl 3 (s) , oF anhydrous aluminum chloride using the data 2 Al(s) + 6 HCl(aq) -→ 2 AlCl 3 (aq) + 3 H 2 (g) Δ H = - 1049 kJ HCl(g) -→ HCl(aq) Δ H = - 74 . 8 kJ H 2 (g) + Cl 2 (g) -→ 2 HCl(g) Δ H = - 185 kJ AlCl 3 (s) -→ AlCl 3 (aq) Δ H = - 323 kJ 1. - 1406 . 8 kJ 2. - 1450 . 85 kJ 3. - 1502 . 4 kJ 4. - 1100 . 36 kJ 5. - 1225 . 7 kJ 6. - 1883 . 5 kJ 7. - 1826 . 2 kJ 003 (part 1 oF 1) 10 points Calculate the standard reaction enthalpy For the reaction.
