Consider the following table:
Gas $a / (kPa \cdot dm^6 \cdot mol^{-2})$ $b / (dm^3 \cdot mol^{-1})$
$A$ $642.32$ $0.05196$
$B$ $155.21$ $0.04136$
$C$ $431.91$ $0.05196$
$D$ $155.21$ $0.4382$

$a$ and $b$ are van der Waals constants. The correct statement about the gases is:

  • A
    Gas $C$ will occupy more volume than gas $A$; gas $B$ will be lesser compressible than gas $D$.
  • B
    Gas $C$ will occupy lesser volume than gas $A$; gas $B$ will be more compressible than gas $D$.
  • C
    Gas $C$ will occupy lesser volume than gas $A$; gas $B$ will be lesser compressible than gas $D$.
  • D
    Gas $C$ will occupy more volume than gas $A$; gas $B$ will be more compressible than gas $D$.

What are the ideal pressure and volume of a real gas?

For $1 \ mol$ of gas,the plot of $pV$ vs $p$ is shown below. $p$ is the pressure and $V$ is the volume of the gas. What is the value of compressibility factor at point $A$?

Assertion : Compressibility factor for hydrogen varies with pressure with positive slope at all pressures.
Reason : Even at low pressure,repulsive forces dominate hydrogen gas.

In the van der Waals equation for gases,what does the constant $b$ represent?

For $1$ mol of a real gas kept at constant temperature $T$,the graph of $PV$ vs $P$ intersects the $PV$ axis at $20$. Hence,the temperature $T$ is ($R$ = universal gas constant).
