Arigid, closed container contains 0.0700 mol of ne(g) and a sample of the solid, ammonium nitirite, nh4no2. assume that the volumes of solids are negligible compared to the volume of the container. the pressure of the ne is meausre at 33 degrees celsius and is found to be .409atm.
the container is then heated to 333 degrees celsius and all of the ammonium nitrite decomposes according to the reaction. nh4no2(s) --> n2(g) + 2h2o(g)
the ne is not involved in the reastion and is still present. the final pressure in the container after complete decompostion of the nh4no2 is 3.93 atm. assuming ideal gas behavior, answer the following questions.
a. what is the volume of the container, in liters?
b. what is the partial pressure of h2o in the containers, at 333 c, when the reaction is complete?
ph2o=

Ответ:
moles Ne = 0.0700 mol
PNe = 0.409 atm
T = 33°C
The reaction is
NH4NO2(s) --> N2(g) + 2H2O(g)
P total = 3.93 atm
a) The volume of the container is
V = nRT/P = 0.07(0.0821)(33 + 273) / (0.409)
Solve for V
b)
The partial pressure of H2O is
PH2O = 3.93 - 0.409
Solve for PH2O
