Gibbs-Duhem equation_____________________?
Correct answer: A. States that n1dμ1 + n2dμ2 + ....njdμj = 0, for a system of definite composition at constant
- A. States that n1dμ1 + n2dμ2 + ....njdμj = 0, for a system of definite composition at constant
- B. temperature and pressure
- C. Applies only to binary systems
- D. Finds no application in gas-liquid equilibria involved in distillation
- E. None of these
Explanation
At constant temperature and pressure, the Gibbs-Duhem relation reduces to Σni dμi = 0. It is useful for multicomponent systems, including gas-liquid equilibrium in distillation, so the intended combined options a and b state the correct condition.
