Consider the following system at equilibrium where H° = 18.8 kJ, and Kc = 9.52×10-2, at 350 K.

CH4(g) + CCl4(g) 2CH2Cl2(g)

If the VOLUME of the equilibrium system is suddenly decreased at constant temperature:

The value of Kc   A. increases.
    B. decreases.
    C. remains the same.

 

The value of Qc   A. is greater than Kc.
    B. is equal to Kc.
    C. is less than Kc.

 

The reaction must:   A. run in the forward direction to reestablish equilibrium.
    B. run in the reverse direction to reestablish equilibrium.
    C. remain the same. It is already at equilibrium.

 

The number of moles of CCl4 will:   A. increase.
    B. decrease.
    C. remain the same.
