1 mole of a diatomic gas present in 10 L...

1 mole of a diatomic gas present in 10 L vessel at certain temperature exert a pressure of 0.96 atm. Under similar conditions an ideal gas exerted 1.0 atm pressure. If volume of gas molecule is negligible, then find the value of van der Waals' constant ''a'' (in atm `L^(2)//mol^(2)`).

Text Solution

Verified by Experts

The correct Answer is:
4
`P+(n^(2)a)/(V^(2))=P_(i)`
`(n^(2)a)/(V^(2))=0.04`
`a=4`
