The equation that represents general van't Hoff equation is

Options

A. `pi=n/(V)RT`
B. `pi=nRT`
C. `pi=V/nRT`
D. `pi=nVRT`

Answer

A

Explanation

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 `Rightarrow piprop C`
If V litres of solution contain n moles of solute, C:
Then, `piV` = constant
(ii) Charles' van't Hoff law `Rightarrowpiprop T `
`pi/T=`Constant
(iii) Avogadro-van't Hoff law `Rightarrowpiprop T` n where, n=number of moles of solute per litre of solution.
