Consider the following system at equilibrium where ΔH° = 10.4 kJ/mol, and Kc = 1.80×10^-2, at 698 K.
2 HI (g) ⇌ H2 (g) + I2 (g)
When 0.31 moles of HI (g) are removed from the equilibrium system at constant temperature:
The value of Kc _________(increase, decrease, remain the same).
The value of Qc _________(increase, decrease, remain the same) than Kc.
The reaction must:
1) run in the forward direction to reestablish equilibrium.
2) run in the reverse direction to reestablish equilibrium.
3) remain the same. It is already at equilibrium.
The concentration of H2 will (increase, decrease, remain the same).
Consider the following system at equilibrium where ΔH° = -108 kJ, and Kc = 77.5, at 600 K.
CO(g) + Cl2(g) ⇌ COCl2(g)
When 0.36 moles of Cl2(g) are added to the equilibrium system at constant temperature:
The value of Kc _________(increase, decrease, remain the same).
The value of Qc _________(increase, decrease, remain the same) than Kc.
The reaction must:
1) run in the forward direction to reestablish equilibrium.
2) run in the reverse direction to reestablish equilibrium.
3) remain the same. It is already at equilibrium.
The concentration of CO will (increase, decrease, remain the same).
