Question

Consider the following system at equilibrium where H° = -108 kJ, and Kc = 77.5, at 600 K.

CO(g) + Cl2(g) COCl2(g)

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

The value of Kc fill in the blank 1 A. increases.
    B. decreases.
    C. remains the same.

 

The value of Qc fill in the blank 2 A. is greater than Kc.
    B. is equal to Kc.
    C. is less than Kc.

 

The reaction must: fill in the blank 3 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 Cl2 will: fill in the blank 4 A. increase.
    B. decrease.
    C. remain the same.
