A : At high pressure , the compressibility factor Z is `(1 + (pb)/(RT))` .
R : At high pressure van der Wall's equation is modified as p(V - b) = RT` .

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Van der Waals equation is
`(P + (a)/(V^2) ) (V - b) = RT`
at high pressure
`P(V - b) = RT`
`rArr (PV)/(RT) = (1+(Pb)/(RT))`
if `(PV)/(RT) = Z`, then `Z = (1+(Pb)/(RT))`
