Chemistry

Consider the following system at equilibrium where Delta H° =108 kJ, and Kc =1.29×10-2, at 600K.

COCl2(g) <--->CO(g)+  Cl2(g)  

If the VOLUME of the equilibrium system issuddenly  increased at constanttemperature:

The value of KcA. increases.
B. decreases.
C. remains the same.
The value of QcA. is greater than Kc.
B. is equal to Kc.
C. is less than Kc.
The reaction must:A. run in the forward direction to reestablishequilibrium.
B. run in the reverse direction to reestablishequilibrium.
C. remain the same. It is already at equilibrium.
The number of moles ofCl2will:A. increase.
B. decrease.
C. remain the same.
