If volume of the gas is very large, then the second virial coefficient

1.	If volume of the gas is very large, then the second virial coefficient B in virial equation is
Answer» `(b+(a)/(RT))` `(b-(a)/(RT))` `(b+(a)/(RTV))` `(b-(a)/(RTV))` Solution :`(P+(a)/(V^(2)))(V-b)=RT` `PV+(a)/(V)-(ab)/(V^(2))-Pb=RT` If V is very large, `(ab)/(V^(2))` can be neglected. HENCE, `PV+(a)/(V)-Pb=RT` or `PV=RT+Pb=(a)/(V)=RT+(RT)/(V)b-(a)/(V)` `=RT[1+(1)/(V)(b-(a)/(RT))]` COMPARING with the virial EQUATION `PV=RT[1+(1)/(B)+...]` `B=b-(a)/(RT)`
