The following equation is the truncated virial equation of state:

$$

$=$

The following equation is the truncated virial equation of state:

where $B(T)$ is the second virial coefficient.

What constraints are there on $B(T)$ if the fluid is to be thermodynamically stable?

where B$($T$)$ is the second virial coefficient.

What constraints are there on B$($T$)$ if the fluid is to be thermodynamically stable?

Please solve this correctly and step by step solution please. Thank you!
