Question

equation of state for real gases -van der waals equation ?​

Answer 1

The van der Waals equation is a stateequation for real gases that modifies the ideal gas equation (PV = nRT) in order to consider intermolecular interactions.

★

equation of state for real gases -van der waals equation is -

$(p \times \frac{a}{ {v}^{2} } )(v - b) = rt \: for \: 1 mole$

OR

$(p + \frac{ {an}^{2} }{ {v}^{2} } )(v - nb) = nrt \: for \: n \: mole$
