At high temperature and low pressure the van der Waals equation is reduced to .

Options

A. `(p + (a)/(V_(m)^(2))) (V_(m)) = RT`
B. `pV_(m) = RT`
C. `p(V_(m) - b) = RT`
D. `(p + (a)/(V_(m)^(2))) = (V_(m) - b) = RT`

Answer

B

Explanation

At high temperature and low pressure, van der Walls equation is reduced to ideal gas equation.
`PV = nRT`
`PV = RT` (For `1` mole of gas)
