Consider the following system at equilibrium where ??° = - 198 kJ, and Kc = 34.5, at 1.15 x 10³ K:
2SO?(g) + O?(g) ? 2SO?(g)
If the temperature on the equilibrium system is suddenly decreased:
The value of Kc
? increases
? decreases
? remains the same
The value of Qc
? is less than Kc
? is greater than Kc
? is equal to Kc
The reaction must
? run in the forward direction to reestablish equilibrium
? run in the reverse direction to reestablish equilibrium
? remain in the current position, since it is already at equilibrium
The concentration of O? will
? increase
? decrease
? remain the same
