2 NO2(g) + N2Oa(g) NO2(g) reacts to form N20a(g) according to the equation above. A pure sample of NO2(g) is placed into a rigid, evacuated 0.500 L container. The initial pressure of the NO2(g) is 960 torr. The temperature is held constant until the NO2(g) reaches equilibrium with its product. The figure below shows how the pressure of the system changes while reaching equilibrium. Pressure (torr) 960 760 Time 7. Which is the correct description of the partial pressures of N204 and NO2? (A) The partial pressures of both N2O4 and NO2 are increasing. (B) The partial pressures of both N204 and NO2 are decreasing. (C) The partial pressure of N204 is increasing twice as fast as that of NO2 is decreasing. (D) The partial pressure of NO2 is decreasing twice as fast as that of N204 is increasing.

2 NO2(g) + N2O4(g) NO2(g) reacts to form N204(g) according to the equation above. A pure sample of NO2(g) is placed into a rigid, evacuated 0.500 L container. The initial pressure of the NO2(g) is 960 torr. The temperature is held constant until the NO2(g) reaches equilibrium with its product. The figure below shows how the pressure of the system changes while reaching equilibrium. Pressure (torr) 960 760 Time 7. Which is the correct description of the partial pressures of N204 and NO2? (A) The partial pressures of both N204 and NO2 are increasing. (B) The partial pressures of both N204 and NO2 are decreasing. (C) The partial pressure of N204 is increasing twice as fast as that of NO2 is decreasing. (D) The partial pressure of NO, is decreasing twice as fast as that of N204 is increasing. 8. The pressure vs. time curve can be used to evaluate (A) only the value of Q. (B) only the equilibrium constant from the horizontal part. (C) only the kinetics of the reaction from the decreasing part. (D) the kinetics of the reaction from the decreasing part and the equilibrium constant from the horizontal part. 9. What will the final pressure be if this reaction goes completion? Based on the data, does this reaction go to completion? (A) 760 torr; yes the reaction goes to completing because this is the given pressure. (B) 240 torr; yes, the reaction goes to completing because it has reached equilibrium. (C) 860 torr; no, the reaction does not go to completion because it is not 860 torr when the reaction stopped. (D) 480 torr; no, the reaction does not go to completion because it is not 480 torr when the reaction stopped.
