For a real gas, the chemical potential is given by_____________________?
Correct answer: B. RT d ln f
- A. RT d ln P
- B. RT d ln f
- C. R d ln f
- D. None of these
Explanation
For a real gas, fugacity replaces pressure in the chemical-potential relation: dμ = RT d ln f at constant temperature. Pressure appears directly only for an ideal gas, where fugacity equals pressure.
