Gibbs-Duhem equation

A. States that n₁dμ₁ + n₂dμ₂ + .... n_jdμ_j = 0, for a system of definite composition at constant temperature and pressure

B. Applies only to binary systems

C. Finds no application in gas-liquid equilibria involved in distillation

D. None of these

Answer: Option A

Solution (By Examveda Team)

The Gibbs-Duhem equation states that $$\sum\nolimits_{i\, = \,1}^n {} {n_i}d{\mu _i} = 0$$
Here the addition to be done for an particular component in different phases.
