The equation that represents general van't Hoff equation is

A

`pi=(n)/(V)RT`

B

`pi=nRT`

C

`pi=(V)/(n)RT`

D

`pi=nVRT`

Text Solution

Verified by Experts

The correct Answer is:
A
The equation that represents van't Hoff general equation is `pi=(n)/(V)RT`
This equation was obtained by combining three laws.
(i) Boyle-van't Hoff law `rArrpiproptoC`
If V litres of solution contain n moles of solute, then `C=(n)/(V).`
`"Then,"piV="constant"`
(ii) Charles'-van'tHoff law `rArrproptoT`
`(pi)/(T)="Constant"`
(iii) Avogadro-van't Hoff law `rArrpropton`
where, n = number of moles of solute per litre of solution.
