Transcribed Image Text:A sample of solid NH4NO3 was placed in an evacuated container and then heated so that it decomposed
explosively according to the following equation:
NH,NO3(s)=N½O(g) + 2H½0(g)
At equilibrium the total pressure in the container was found to be 2.34 atm at a temperature of 500.°C.
Calculate Kp.

Expert Solution

Step 1
The given equilibrium is
NH4NO3 (s) --------> N2O (g) + 2 H2O (g)
The equilibrium constant for the given reaction is
KP = pN2O * p H2O2
(the partial pressure of a solid is taken as unity. That is pNH4NO3 (s) = 1)
