For a certain gas which deviates a little from ideal behaviour, a plot between P/p vs P was found to be non- linear . The intercept on y-axis will be :

A

`(RT)/(M)`

B

`(M)/(RT)`

C

`(MZ)/(RT)`

D

`(R)/("TM")`

Text Solution

Verified by Experts

The correct Answer is:
a

(a) `P(V-nb)=nRT`
`PV-P" n "b=nRT " "d=("Mass")/("Volume")`
`PV=nRT+P" n "b" " n=("Mass")/(M)`
`P("Mass")/(d)=nRT+P" n "b `
`(P)/(d)=(n)/("Mass")RT+(P" n "b)/("Mass")`
`(P)/(d)=(RT)/(M)+(Pb)/(M)`
