For an ideal gas, the chemical potential is given by
A. RT dlnP
B. R dlnP
C. R dlnf
D. None of these
Answer: Option A
Solution (By Examveda Team)
Since for an ideal gas mixture : $$fugacity= pressure$$\[\begin{array}{l} d\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\smile$}} \over G} = RTdlnP\\ \Rightarrow d{\mu _i} = RTdlnP \end{array}\]
