The value of K.
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 Cl, will:
A. increase.
B. decrease.
C. remain the same.
