Question

At low pressure, the van der Waal's equation is written as
A) PV/RT=[1-a/RTV]
B) PV/RT=[1-RTV/A]
C) PV/RT=[1+a/RTV
D) PV/RT=[1+RTV/a​

Answer 1

Answer:

$[P+ </p><p>V </p><p>2</p><p> </p><p>a</p><p> </p><p> ][V−b]=RT</p><p>At low pressure,volume correction left b right may be neglected.</p><p>Thus,</p><p>[P+ </p><p>V </p><p>2</p><p> </p><p>a</p><p> </p><p> ][V−b]=RT</p><p>Or</p><p>PV+ </p><p>V</p><p>a</p><p> </p><p> =RT</p><p>Or</p><p>PV=RT[1− </p><p>RTV</p><p>a</p><p> </p><p> ]$
