Options

  1. AA-p; B-q; C-p; D-q, r
  2. BA-p, q; B-r; C-r, s; D-p, q
  3. CA-s; B-p; C-p; D-q
  4. DA-p, s; B-r; C-p, q; D-r

Correct answer

D. A-p, s; B-r; C-p, q; D-r

Step-by-step solution

(A) -p, s( ~B )-r (C) -p, q (D) -r Explanation van der Waals' equation (p+ n^2 a V_m^2 ) (V_m-b )=n R T For hydrogen gas (p=200 ~atm , T=273 ~K ) As pressure is large V_m can be assumed small, thus ' b ' can not be ignored, while due to high pressure a / V_m^2 can be considered negligible in comparison to p . p (V_m-b )=R T and Z=1+ p b R T For hydrogen gas (p 0, T=273 ~K ) when pressure occurs of low about 1 ~atm or less and temperature is not very close to the point of liquification [T_c ( H ₂ )=33.3 ~K ] gas beh
