A sealed faskintally contains pure nitrogen dioxide gas (NO2) Over time the nitrogen dioxide forms dinitrogen tetroxide gas N20) The graph below shows the relative amounts of (NO2) and (N2O2) over time What is true about the time indicated by the blue arrow

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
