Question


Consider the following system at equilibrium where H° = -18.8 kJ/mol, and Kc = 10.5 , at 350 K.

CH2Cl2 (g)  CH4 (g) + CCl4 (g)

When 0.21 moles of CH2Cl2 (g) are removed from 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 CH4 will _________ (increase, decrease or remain the same)
