1 mole of each of `X_(1),X_(2),X_(3)` with van der Waal's constants a (in atm `L^(3) mol^(-2)`) 1.0, 3.8, 2.1 respectively is kept separately in three different vessels of equal volume at identical temperature. Their pressures are observed to `P_(1),P_(2),` and `P_(3)` respectively. On the basis of this data alone, select the correct option (neglect the effect of 'b') :

A

`P_(1)ltP_(2)ltP_(3)`

B

`P_(2)ltP_(1)ltP_(3)`

C

`P_(2)ltP_(3)ltP_(1)`

D

`P_(1)=P_(2)=P_(3)`

Text Solution

Verified by Experts

The correct Answer is:

(c) `P_("Real")=P_(i)-(n^(2)a)/(V^(2))`
`a uarr P_(r)darr`
`P_(2)ltP_(3)ltP_(1)`
