Consider the following system at equilibrium where AHP -104 kJ/mol and K, 5.6, at 698 H2 (g) +12 (g)=: 2 H1@ When 0.20 moles of HI (g) are removed from the equilibrium system at constant temperature: The value of Kc . The value ofQc · Be. The reaction must Orun in the forward direction to restablish equilibrium. Orun in the reverse direction to restablish equilibrium. remain the same. It is already at equilibrium. The concentration of 12 will Ratry Entire Group 00 or 400 level in General

Explanation / Answer

For the reaction

H2(g) + I2(g) <==> 2HI(g)

When 0.20 mol HI is removed,

The value of Kc = remain the same

The value of Qc = will decrease

The reaction must,

run in the forward direction to reestablish equilibrium

The concentration of I2 will decrease

-----

For the reaction

H2(g) + I2(g) <==> 2HI(g)

When 0.25 mol I2 is added,

The value of Kc = remain the same

The value of Qc = will decrease

The reaction must,

run in the forward direction to reestablish equilibrium

The concentration of H2 will decrease
