Question

Consider the following system at equilibrium where H° = -111 kJ/mol, and K_c = 0.159, at 723 K.

N₂(g) + 3H₂(g) 2NH₃(g)

If the TEMPERATURE on the equilibrium system is suddenly increased:

The value of K_c		A. increases.
		B. decreases.
		C. remains the same.

The value of Q		A. is greater than K_c.
		B. is equal to K_c.
		C. is less than K_c.

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 concentration of H₂ will:		A. increase.
		B. decrease.
		C. remain the same.
