Consider the dissociation of NH4NO3(s) Into vapor phase N2O(g) and H2O(g). a. Write a balanced equation for this reaction b. Equilibrium Expression c. At 319 degrees Celsius, the pressure is 1728 Pa. Calculate the equilibrium constant at that temperature d. Given that delta G for this reaction is 54.32 kJ/mol and delta H for this reaction is 178 kJ/mol-1, calculate delta S e. Calculate the equilibrium constant at 351 K

Explanation / Answer

a) Balanced equation:

NH3NO3 -> N2O + 2H2O

b ) The equilibrium expression:

Kc = [Products]/[Reactants]

Kc = [H2O]2[N2O]/[NH4NO3]

Since solids have concentraitn of 1

Kc = [H2O]2[N2O]

c) P = 1728 T= 319 C or 592 K

Use ideal gas law

Kc = [H2O]2[N2O]

Or let use partial pressures... Given:

P
