Ammonia gas, NH3 (g), can be prepared according to the
equilibrium below (to be called “the system” henceforth):
N2 (g) + 3H2 (g) ⇌ 2NH3 (g) Kc = 1.2 (at 375 0 C); ΔH0 = - 92
kJ
A) Please calculate Kp for this equilibrium.
B) Please determine Kp for the decomposition of ammonia into its elements
C) Please determine the value of Qc given [NH3] = 0.110 M, [H2] = 0.099 M, and [N2] = 10.1 M.
D) Please propose which way the system will shift to attain equilibrium (answer one of l -> r, r -> l, or no shift).
E) Please fill in the following gaps with one of: l -> r, r
-> l, or no shift:
If cooled to 150 0 C, the system will shift __________
If ammonia gas is removed as it forms, the system will shift
__________
If the system is compressed, it will shift __________
