Chemistry Question on States of matter

The expression for van der Waals equation for the gas law is

A

nRT = (P+a/V2)(V−b)(P + a/V^2) (V - b)

B

nRT = (P−a/V2)(V−b)(P- a/V^2) (V - b)

C

nRT = (P+a/V2)(V+b)(P + a/V^2) (V + b)

D

nRT =(P+a2/V2)(V−b) (P+ a^2/V^2) (V - b)

Answer

nRT = (P−a/V2)(V−b)(P- a/V^2) (V - b)

Explanation

Solution

van der Waals equation of state is
[P+an2V2]\left[ P + \frac{an^2}{V^2} \right] [V - nb] = nRT
