Question
Consider the following system at equilibrium where H° = -111 kJ, and Kc = 0.159, at 723 K.
N2(g) + 3H2(g) 2NH3(g)
When 0.21 moles of H2(g) are added to the equilibrium system at constant temperature:

The value of Qc _________is (greater than, is equal to, is less than) Kc.
The reaction must
a. run in the forward direction to restablish equilibrium.
b. run in the reverse direction to restablish equilibrium.
c. remain the same. It is already at equilibrium.
b. run in the reverse direction to restablish equilibrium.
c. remain the same. It is already at equilibrium.
