Question

Decide whether the brief descriptions or terms in the left column are related to the hard sphere model, van der Waals' model, or both models in the right column.

has a 'b' term

both models            van der Waals' model            hard sphere model      

accounts for real volume

both models            van der Waals' model            hard sphere model      

has an 'a' term

both models            van der Waals' model            hard sphere model      

accounts for IMF

both models            van der Waals' model            hard sphere model      

Explanation / Answer

Van der waals equation: (P + (n2 a/V2 ))(V-nb) = nRT

Hard spere equation: P(V-nb) =nRT

has a 'b' term: both models  

accounts for real volume: both models  

has an 'a' term: van der Waals' model

accounts for IMF: both models
