Question

A.) Consider the following system at equilibrium where Kc = 6.30 and H° = 111 kJ/mol at 723 K.

NH3 (g)  N2 (g) + H2 (g)

The production of N2 (g) is favored by:

Indicate True (T) or False (F) for each of the following:
 1. decreasing the temperature.

2. increasing the pressure (by changing the volume).

 3. decreasing the volume.

 4. removing NH3 .

 5. removing H2 .

B.) Consider the following system at equilibrium where Kc = 0.159 and H° = -111 kJ/mol at 723 K.


N2 (g) + H2 (g)  NH3 (g)

The production of NH3 (g) is favored by:
