Consider the following table :
Gas
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 :
Gas C will occupy more volume than gas A;
gas B will be more compressible than gas D
Gas C will occupy lesser volume than gas A;
gas B will be lesser compressible than gas D
Gas C will occupy more volume than gas A;
gas B will be lesser compressible than gas D
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.
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
