Consider the following statements. If the van der Waals' parameters of two gases are given as

                                a/dm6 bar mol-2                               b/dm3 mol-1
Gas A                                6.5                                                 0.055
Gas B                                  2                                                     0.01

then:

1.  Critical volume of A > Critical volume of B
2.  Critical pressure A > Critical temperature of B
3.  Critical temperature of A > Critical temperature of B

Which of the above statement is incorrect?

1.  1 alone

2.  1 and 2
