Question description

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

2CH2Cl2(g) CH4(g) + CCl4(g) 

If the TEMPERATURE on the equilibrium system is suddenly decreased:

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 restablish equilibrium.
B. Run in the reverse direction to restablish equilibrium.
C. Remain the same. Already at equilibrium.

The concentration of CCl4 will:A. Increase.
B. Decrease.
C. Remain the sam
