Consider the following statements. If the van der Waal' s parameters of two gases are given as
\( \begin{array}{ccc} & a / \mathrm{dm}^{6} \mathrm{bar} \mathrm{mol}^{-2} & b / \mathrm{dm}^{3} \mathrm{~mol}^{-1} \\ \text { Gas } A & 6.5 & 0.055 \\ \text { Gas } B & 2 & 0.01\end{array} \)
then :
1. Critical volume of \( A \) Critical volume of \( B \)
2. Critical pressure \( A \) Critical pressure of \( B \)
3. Critical temperature of \( A \) Critical temperature of \( B \)
Which of the above statements is/are incorrect?
(a) 1 alone
(b) 1 and 2
(c) 1,2 and 3
(d) 2 and 3
