Solution

The correct option is A $I$
$P (V - b) = R T$
$d = \frac{R}{(V - b)} . T \Rightarrow s l o p e = \frac{R}{V - b}$
$P V - P b = R T$
$V = \frac{R T}{P} + b$ $s l o p e = \frac{R}{P}$ an intercept $b$
$V = \frac{P V}{R T} = 1 + \frac{P b}{R T}; Z > 1$
i.e., repulsive forces predominate.

A gas obeys P(V−b)=RT. Which of the following are correct about this gas?I. Isochoriccurveshaveslope=RV−bII. isobaric curves have slope RP and intercept b.III. Forthegascompressibilityfactor=1+RbRT.IV. The attraction forces are overcome by repulsive forces.

The correct option is A IP(V−b)=RTd=R(V−b).T⇒slope=RV−bPV−Pb=RTV=RTP+b slope=RP an intercept bV=PVRT=1+PbRT;Z>1i.e., repulsive forces predominate.

The correct option is A $I$
$P (V - b) = R T$
$d = \frac{R}{(V - b)} . T \Rightarrow s l o p e = \frac{R}{V - b}$
$P V - P b = R T$
$V = \frac{R T}{P} + b$ $s l o p e = \frac{R}{P}$ an intercept $b$
$V = \frac{P V}{R T} = 1 + \frac{P b}{R T}; Z > 1$
i.e., repulsive forces predominate.
