Consider the following system at equilibrium
where H°
= 182 kJ, and
Kc = 7.00×10-5,
at 673 K.

NH4I(s) NH3(g)
+ HI(g)

When some moles of NH4I(s)
are added to the equilibrium system at
constant temperature:
The value of Kc ???? (Increases, decreases,
remains the same)
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.
The concentration of NH3
will ???( increase, decrease, remain the same.)
