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 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. What will the final pressure be if this reaction goes reaction go to completion? completion? Based on the data, does this (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.
