At room temperature following reaction goes to cormpletion `2NO+O_(2) rarr 2NO_(2)rarr N_(2)O_(4)`
Dimer `N_(2)O_(2)" at "262 K` is solid. A 250 ml flask and a 100 ml flask are separated by a stop cock. At 300 K, the nitric oxide in the larger flask exerts a pressure of 1.053 atm and the smaller one contains `O_(2)" at "0.789` atm. The gases are mixed by opening the stop cock and after the. end of the reaction, the flasks are cooled to 220 K. Neglecting the vapour pressure of dimer find out the pressure and composition of gas remaining at 220 K. (Assume gases behave ideàlly).

At room temperature, the following reaction proceeds nearly to completion: 2NO+O_(2)to2NO_(2)toN_(2)O_(4) The dimer, N_(2)O_(4) , solidfies 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 gase are mixed by opening the stopcock and after the end of the reaction the flasks are cooled to 220 K . Neglecting the vapour pressure of the dimer, find out the pressure and composition of the gas remaining at 220 K . (Assume the gases to behave ideally)

At room temperature following traction goes to completion 2AB(g)+B_(2)(g)rarr2AB_(2)(s) AB_(2) is solid with negligble vapour pressure below 0^(@)C . At 300 K, the AB in the smaller flask exerts a pressure of 3 atm and in the larger flask B_(2) exerts a pressure of 1 atm at 400 K when they are separated out by a close valve, The gases are mixed by opening the stop cock and after the end of the reaction the flask are cooled to 250 K The final pressure is :

N_(2) is found in a litre flask under 100 k Pa pressure and O_(2) is found in another 3 litre flask under 20 K Pa pressure. If the two flask are connected, the resultant pressure is

Four one litre flaske are separately filled with the gases H_(2), He, O_(2) "and" O_(3) at the same temperature and pressure. The ratio of total number of atoms of these gases present in different flask would be:

Four 1-1 litre flasks are seperately filled with the gases H_(2) , He and O_(2) and O_(3) at the same temperature and pressure. The ratio of total number of atomsof these gases present in different flask would be:
