# Consider the following table :Gas                   A                           642.32                                      0.05196B                          155.21                                       0.04136C                          431.91                                       0.05196D                          155.21                                       0.4382               a and b are van der Waals constants. The correct statement about the gases is :Option 1)Gas C will occupy more volume than gas A; gas B will be more compressible than gas DOption 2)Gas C will occupy lesser volume than gas A; gas B will be lesser compressible than gas DOption 3)Gas C will occupy more volume than gas A; gas B will be lesser compressible than gas DOption 4)Gas C will occupy lesser volume than gas A; gas B will be more compressible than gas D

In Vanderwaal's equation,

a & b are constants

Here 'a' is defined as greater the value of 'a' ,

greater is the force of attraction & smaller is the volume.

& ' b ' is defined the greater the value of ' b ' , higher will

be the effective volume & less will be the compressibility.

Gas 'C' will occupy more volume than Gas 'A' , Gas 'B'

will be more compressible than Gas 'D'.

option (1) is correct.

Option 1)

Gas C will occupy more volume than gas A;

gas B will be more compressible than gas D

Option 2)

Gas C will occupy lesser volume than gas A;

gas B will be lesser compressible than gas D

Option 3)

Gas C will occupy more volume than gas A;

gas B will be lesser compressible than gas D

Option 4)

Gas C will occupy lesser volume than gas A;

gas B will be more compressible than gas D
