Which of the following represents the van der Walls equation for `n` moles of a real gas ?

Options

A. (a) `(P + (a)/(V^(2))) (V-b) = nRT`
B. (b) `(P + (a)/(nV^(2))) (V-nb) = nRT`
C. (c) `(P + (n^(2) a)/(V^(2))) (V-nb) = nRT`
D. (d) `(P + (na)/(V^(2))) (V-nb) = nRT`

Answer

C

Explanation

Van der Waal equation : `(P + (n^(2)a)/(V^(2))) (V- nb) = nRT`
