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 : $$fugacity= pressure$$
\[\begin{array}{l} d\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\smile$}} \over G} = RTdlnP\\ \Rightarrow d{\mu _i} = RTdlnP \end{array}\]
