1.	A gas obeys P(V-b) = RT. Then which of the following are correct
Answer» Isochoric curves have the slope = R/V-B Isobaric curves have the slope =R/P with INTERCEPT = b For the gas compressibility factor = 1+ Pb/RT Attractive forces predominate REPULSIVE forces Solution :a) Isochoric = V constant `P(V- b) = RT , P = ((R )/(V-b))^(T)` , slope = `R/(V-b)` b) Isobaric = P constant `(Vb) = (R/P)^T , V = (R/P)^T + b` slope= `R/P`, constant = b c) `P (V- b) = RT, PV e= RT + Pb` `(PV)/(RT) =1+ (b/(RT))P` ` Z > 1` = repulsive forces dominate.
