For the equilibrium NH4NO3(s) ⇌ N2O(g) + 2H2O(g), the value of KP at 500 K is 4×3λ/2 atm3 and the total equilibrium pressure is 9 atm. The value of λ is

Options:

Answer:
B
Solution:

Gas moles per mole of solid: N2O = 1, H2O = 2, total = 3 Mole fractions: N2O = 1/3 and H2O = 2/3

Partial pressures at 9 atm: N2O = 3 atm and H2O = 6 atm

KP = (3)(6)2 = 108

108 = 4×27 = 4×33

3λ/2 = 33 so λ/2 = 3

λ = 6

This is option (b).
