Consider the following equilibrium: 2NO₂ (g) N₂O₂(g) AG=-5.4 kJ Now suppose a reaction vessel is filled with 6.98 atm of dinitrogen tetroxide (N₂O) at 1001. °C. Answer the following questions about this system: Under these conditions, will the pressure of N₂O tend to rise or fall? Is it possible to reverse this tendency by adding NO₂? In other words, if you said the pressure of N₂O₂ will tend to rise, can that be changed to a tendency to fall by adding NO₂? Similarly, if you said the pressure of N₂O will tend to fall, can that be changed to a tendency to rise by adding NO₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO, needed to reverse it. Round your answer to 2 significant digits. rise O fall O yes O no X
