The equation that represents general  van’t Hoff equation  is

Answer:

Explanation:

 The equation that represents van't Hoff general equation $\pi =\frac{n}{V}RT$

 This equation was obtained by combining three laws.

  (i)    Boyle-van't Hoff law $\Rightarrow$  $\pi \propto C$

 If V litres of solution contains n moles of solute,

 then C=$\frac{n}{V}$

Then, $\pi V$ = constant

(ii)     Charles'-van't Hoff law $\Rightarrow$  $\pi \propto T$

$\frac{\pi}{T}$= Constant

(iii)  Avogadro- van't Hoff law $\Rightarrow$   $\pi \propto n$

where, n= number of moles of solute  per litre of solution
