At what absolute temperature the pressure of He gas in a definite volume become equal to zero?

Question

At what absolute temperature the pressure of He gas in a definite volume become equal to zero? (A) (a/R) × ((V m -b)2/V m 2) (B) (a/R) × ((V m -b)/V m 2) (C) (a/R) × ((V m -b)2/V m ) (D) (a V m /R)

(P+(a/V m 2))(v m -b)=R T when P=O, T=(a/R) × ((v m -b)/V m 2)

Q. At what absolute temperature the pressure of $He$ gas in a definite volume become equal to zero?

$\frac{a}{R} \times \frac{( V _{m} - b ) ^{2}}{V _{m}^{2}}$

$\frac{a}{R} \times \frac{( V _{m} - b )}{V _{m}^{2}}$

$\frac{a}{R} \times \frac{( V _{m} - b ) ^{2}}{V _{m}}$

$\frac{a V _{m}}{R}$

$(P + \frac{a}{V _{m}^{2}}) (v_{m} - b) = RT$

when $P = O, T = \frac{a}{R} \times \frac{( v _{m} - b )}{V _{m}^{2}}$
