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

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)
