In van der Waals equation of state for a non-ideal gas , the term that accounts for intermolecular forces is

Options

A. (V- b)
B. RT
C. `(P + (a)/(V^(2)))`
D. `(RT)^(-1)`

Answer

C

Explanation

`P_("correction") = (an^(2))/(v^(2))`
`P_("ideal") = ( P + (an^(2))/(v^(2)))` for 1 mole `P_("ideal") = (P + (a)/(v^(2)))` responsible for intermolecular force .
