MCQ
In Vander Waal’s equation $a$ and $b$ represent $\left( {P + \frac{a}{{{V^2}}}} \right)\,(V - b) = RT$
  • A
    Both $a$ and $b$ represent correction in volume
  • B
    Both $a$ and $b$ represent adhesive force between molecules
  • $a$ represents adhesive force between molecules and $b$ correction in volume
  • D
    $a$ represents correction in volume and $b$ represents adhesive force between molecules

Answer

Correct option: C.
$a$ represents adhesive force between molecules and $b$ correction in volume
c
$\left(P+\frac{a n^{2}}{V^{2}}\right)(v-n b)=n R T$

The constants $a$ and $b$ represents the magnitude of intermolecular attraction and excluded volume respectively, and are specific to a particular gas.

Correct choice - option - $C$
