The reaction of dimerisation of NO_(2) in N_(2)O_(4) is 2NO_(2)hArrN_(2)O_(4). The reaction is carried out by taking 1 mole each of NO_(2) and N_(2)O_(4) in a closed vessel of 1 litre at 400 K. The equilibrium pressure was found to be 77 atm. Addition of one mole of an inert gas to the above equilibrium shows that degree of dissociation and equilibrium pressure of N_(2)O_(4) is

1.	The reaction of dimerisation of NO_(2) in N_(2)O_(4) is 2NO_(2)hArrN_(2)O_(4). The reaction is carried out by taking 1 mole each of NO_(2) and N_(2)O_(4) in a closed vessel of 1 litre at 400 K.

Answer» `prop` decrease, `P=77 atm` `prop` increase, `P=77 atm` `prop` does not change, `P=110.0 atm` `prop` DECREASES, `P=110.0 atm` Solution :The DISSOCIATION of `N_(2)O_(4)` remains unaffected since addition of inert gas at CONSTANT volumedoes not change `'alpha'` ALSO `P=3.35xx0.0821xx400=110 atm`
