At room temperature, the following reaction proceeds nearly to completion.
The dimer, , solidifies at . A flask and a flask are separated by a stopcock. At , the nitric oxide in the larger flask exerts a pressure of 1.053 atm and the smaller one contains oxygen at .
The gases are mixed by opening the stopcock and after the end of the reaction, the flasks are cooled to . Neglecting the vapor pressure of the dimer, find out the pressure and composition of the gas remaining at . (Assume the gases to behave ideally).

First we calculate partial pressure of and in the combined system when no reaction taken place.
Now the reaction stoichiometry can be worked out using partial pressure because in a mixture.
Now, on cooling to will solidify and only unreacted will be remaining in the flask.
