Question

Consider the following statements.
If the van der waal's parameter of two gases are given as

$a\left(atm{L}^{2}mo{l}^{-2}\right)b\left(L^{2}mo{l}^{-1}\right)$
Gas X: $6.50056$
Gas Y: $8.00011$

Then $A:V_c\left(X\right)<V_c\left(Y\right)$
$B:p_c\left(X\right)<p_c\left(Y\right)$
$C:T_c\left(X\right)<T_c\left(Y\right)$

Select the correct alternate.

• A. A alone
• B. A and B
• C. A, B and C
• D. B and C

Answer 1

The correct option is D

B and C

$V_c=3b$
$P_c=\frac{a}{27b^2}$
$T_c=\frac{8a}{27Rb}$

From the table given compute the above 3 critical constants for gas and conclude the answer.
