Question

why constant b neglect the term a/v^2 in the van der waals deviation at high pressure ​

Answer 1

Answer: at high pressure attraction are negligible.

Explanation:

(P+an2/v2)(V-nb) =nRT

an2/v2 is attractive forces measures. We. Can neglecte an2/v2

P value is very high if u add less value no change in total value.

Example volume is 100 litre if you add 1 ml Water no considerable change so we can neglect 1 ml compare to 100 litres same in case of pressure.
