7. Calculate the AH for the following reaction: 2N2 (g) +502 (9) 2N205 (9) 4NO2 (g) + O2 (g) 2N205 (9) 2NO (g) + O2 (g) 2N02 (9) N2 (g) + O2 (g) 2NO(g) - AH= -110.2 kJ AH= -114.1 kJ AH= 180.5 kJ (a) 22.6 kJ (b)-22.6 kJ (c)-228.2 kJ (d) -588.3 kJ 8. Calculate the AS for the following reaction: 2N2 (g) + 5O2 (g) 2N2O5 (9) Sm(N2 (9)) = 191.6 J/(K mol), SmCO2 (g)) = 205.1 J/(K mol), Sm(N2O5 (9)) = 355.6 J/(K mol) (a) -697.5 J/K (b) 0 JK (C) -41.1 J/K 9. Calculate the K value at 30 degrees Celsius for the reaction: 2N2 (9) + 502 (g) 2N205 (9) Hint: Your work from #7 and #8 will help you with answering this question and #10. (a) 99.6 (b) e-92.9 (c) a negative number very close to zero (d) 8525929.5
