Question
Consider the following system at equilibrium where H° = 10.4 kJ, and Kc = 1.80×10-2, at 698 K.
2HI(g) ---> H2(g) + I2(g)
When 0.28 moles of H2(g) are removed from the equilibrium system at constant temperature:
The value of Kc _____ (INCREASES, DECREASES, STAYS THE SAME)
The value of Qc ______ (GREATER THAN, LESS THAN, OR EQUAL TO) Kc
The reaction must:
1 run in the forward direction to restablish equilibrium.
2 run in the reverse direction to restablish equilibrium.
3 remain the same. It is already at equilibrium.
2 run in the reverse direction to restablish equilibrium.
3 remain the same. It is already at equilibrium.
The concentration of I2 will ______ (INCREASE, DECREASE, STAY THE SAME)
