Question
Which of the following is the correct expression for the equation of state of van der Waals gas?
Options
`["P" + "a"/("n"^2"V"^2)]("V" - "nb") = "nRT"`
`["P" + "na"/("n"^2"V"^2)]("V" - "nb") = "nRT"`
`["P" + "an"^2/("V"^2)]("V" - "nb") = "nRT"`
`["P" + ("n"^2"a"^2)/("V"^2)]("V" - "nb") = "nRT"`
