Consider the following table:

a and b are van de Waals constants. The correct statements about the gases is:

Options

A. Gas C will occupy more volume than gas A , gas B will be more compressible than gas D
B. Gas C will occupy more volume than gas A, gas B will be lesser compressible than gas D
C. Gas C will occupy lesser volume than gas A, gas B will be more compressible than gas D
D. Gas C will occupy lesser volume than gas A , gas B will be lesser compressible than gas D

Answer

A

Explanation

For gases A and C ,.b. value is same so gas having higher value of .a. i.e., higher force of attraction will have lesser volume .Gas C will have higher volume . For B and D , .a. value is same , so gas having higher value of .b. will be less compressible .
` :. Z = 1 - a/(VRT) +(Pb)/(RT)`
` :. ` gas B will be more compressible .
