At room temperature, the following reaction proceeds nearly to completion.
`2NO + O_(2) rarr 2NO_(2) rarr N_(2)O_(4)`
The dimer, `N_(2)O_(4)` , solidifies at 262 K. A 250 mL flask and a 100 mL flask are separated by a stopcock. At 300 K, the nitric oxide in the larger flask exerts a pressure of 1.053 atm and the smaller one contains oxygen at 0.789 atm.
The gases are mixed by opening the stopcock and after the end of the reaction the flasks are cooled to 220 K. Neglecting the vapor pressure of the dimer, find out the pressure and composition of the gas remaining at 220 K. (Assume the gases to behave ideally).
