Answer : Option B
Explanation :
We know the property relation dG=VdP−sdT for constant temperature dT=0
For an ideal gas
dG=VdPdG=RTPdP⇒dG=RTdlnP
For a real gas also if we want to describe the relation in the same functional form we express it as dG=RTdlnf⇒dμ=RTdlnf where f= fugacity, that means we buried the entire non ideality in this term fugacity. The term fugacity is also called as effective pressure.
