The value of the equilibrium constant, Kp for the reaction below is 3.1 × 10-4 at 700K.
N2 (g) + 3H2 (g) ↔ 2NH3 (g)
Given the initial partial pressure of the gases, PN2 = 0.411 atm; PH2 = 0.903 atm; PNH3 = 0.224 atm, calculate the value of the reaction quotient, Q.
Q = 0.0437
Q = 0.1658
Q = 0.6036
Q = 0.1352

The value of the equilibrium constant, Kp for the reaction below is 3.1 × 10-4 at 700K.
N2 (g) + 3H2 (g) ↔ 2NH3 (g)
Given the initial partial pressure of the gases, PN2 = 0.411 atm; PH2 = 0.903 atm; PNH3 = 0.224 atm. Predict the direction in which the reaction will proceed at 700 K.
Since Q > Kp, the equilibrium will proceed to the left to bring the value Q down to 3.1 × 10-4.
Since Q > Kp, the equilibrium will proceed to the right to bring the value Q down to 3.1 × 10-4.
Since Q > Kp, the equilibrium will proceed to the left to bring the value Q up to 3.1 × 10-4.
Since Q > Kp, the equilibrium will proceed to the right to bring the value Q up to 3.1 × 10-4.

For the reaction system:
2HI (g) ↔ H2 (g) + I2 (g)
Kc = 0.020 at 720 K
If the initial concentrations of HI, H2 and I2 are all 1.50 × 10-3 M at 720 K, which one of the following statements is correct?
The system is at equilibrium.
The concentrations of HI and I2 will increase as the system is approaching equilibrium.
The concentration of HI will increase as the system is approaching equilibrium.
The concentration of H2 and I2 will increase as the system is approaching equilibrium.

For the reaction, N2O4 (g) ↔ 2NO2 (g), Kc = 0.21 at 100oC. At initial, the [N2O4] = 0.12 M and [NO2] = 0.55 M. Is the reaction at equilibrium? If not, in which direction it is progressing?
Yes, the reaction is at equilibrium.
No, the reaction is not at equilibrium. Qc < Kc, therefore the reaction will proceed from left to right until Qc = Kc.
No, the reaction is not at equilibrium. Qc > Kc, therefore the reaction will proceed from right to left until Qc = Kc.
No, the reaction is not at equilibrium. Qc < Kc, therefore the reaction will proceed from right to left until Qc = Kc.
