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. The numerical value of K_(c) and K_(p) the reaction actually taking place in container is :

Answer»

`4.44,145.8`
`0.23,7.56`
`146.13,4.8xx10^(3)`
`6.8xx10^(-3),6`

Solution :`K_(C)=((1.70)^(2))/0.65=4.44` and
`K_(p)=K_(c)xx(RT)^(DELTAN)`
`=4.44xx0.0821xx400=145.8`
