1) 2NO(g) + O2(g)2NO2(g) Using standard absolute entropies at 298K, calculate the entropy change for the system when 1.83 moles of NO(g) react at standard conditions.
S°system = J/K
2) 2NO(g) + 2H2(g)N2(g) + 2H2O(l)
Using standard absolute entropies at 298K, calculate the entropy change for the system when 1.95 moles of NO(g) react at standard conditions.
S°system = J/K
