Consider the following system at equilibrium where H° = -111 kJ, and Kc = 0.159 , at 723 K: N2 (g) + 3 H2 (g) 2 NH3 (g)
If the TEMPERATURE on the equilibrium system is suddenly decreased :
The value of Kc A. 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 H2 will: A. Increase. B. Decrease. C. Remain the same.
