Correct answer
CGas will occupy more volume than gas ; gas will be more compressible than gas
Step-by-step explanation
* Gas A and C have same value of ‘b’ but different value of a so gas having higher value of a have more force of attraction so molecules will be more closer hence occupy less volume.
* Gas B and D have same value of ‘a’ but different value of b so gas having lesser value of b will be more compressible.
* Gas B and D have same value of ‘a’ but different value of b so gas having lesser value of b will be more compressible.
