Consider the following table : Gas a/(k Pa dm 6 mol –1 ) b/(dm 3 mol –1 ) A 642.32 0.05196 B 155.21 0.04136 C 431.91 0.05196 D 155.21 0.4382 a and b are vander Waals constants. The correct statement about the gases is :

1. Gas C will occupy more volume than gas A; gas B will be more compressible than gas D
2. Gas C will occupy lesser volume than gas A; gas B will be more compressible than gas D
3. Gas C will occupy lesser volume than gas A; gas B will be lesser compressible than gas D
4. Gas C will occupy more volume than gas A; gas B will be lesser compressible than gas D

Correct answer: Gas C will occupy more volume than gas A; gas B will be more compressible than gas D
