If 92g of N2O4 is taken in a closed vessel and heated till equilibrium is reached. At equilibrium, 50% of N2O4 is dissociated by the reaction N2O4 to 2NO2. The equilibrium constant for the reaction is:

Two flasks A and B of equal volume containing NH3 and HCl gases are connected by a narrow tube of negligible volume. The two gases were prevented from mixing by stopper fitted in connecting tube. For further detail of experiment refer to the given figure. What will be the final pressure in each flask when passage connecting the two tubes are opened.
