Consider the following table:
Gas a/ (k Pa 
) b/ 
)
A 642.32 0.05196
B 155.21 0.04136
C 431.91 0.05196
D 155.21 0.4382
a and b are van der waals constants. The correct statement about the gases is :

JEE Main 2019
If values of ‘b’ for two gases are same but values of ‘a’ are different, then the gas having a larger value of ‘a’ will occupy lesser volume. Since, it, will have larger force of attraction and, therefore, lesser distance between its molecules. If values of ‘a’ for two gases are same but values of ‘b’, are different then the smaller value of ‘b’ will occupy lesser volume and, therefore, will be more compressible.
