Question

A gas obeys the van der waals equation. Calculate the constants a and $b$ for this gas approximately.

(A) $1.88 \times 10^{6} cc ^{2} atm / mole ^{2}, 120 cc / mole$

(B) $3.16 \times 10^{6} cc ^{2} atm / mole ^{2}, 30 cc / mole$

(C) $3.16 \times 10^{6} cc ^{2} atm / mole ^{2}, 50 cc / mole$

(D) $0.86 \times 10^{5} cc ^{2} atm / mole ^{2}, 30 cc / mole$

Answer 1

The constants a and b for this gas approximately will be $3.16 \times 10^{6} cc ^{2} atm / mole ^{2}, 30 cc / mole$.

So, The correct option of this question is (B).
