WebQuestion: a) We have a mixture of water and alcohol in equilibrium with its vapours. Using the Duhem theorem, calculate the number of intensive variables required for the system. (b) If the equilibrium curve is below the diagonal line and y and x are the mole fractions of the more volatile component in vapour and liquid phase. WebSep 23, 2024 · Euler’s theorem is a general statement about a certain class of functions known as homogeneous functions of degree . Consider a function of variables that satisfies for an arbitrary parameter, . We call such a function a homogeneous function of degree in the variables . The function , for example, is a homogeneous function of degree .

In thermodynamics, the Gibbs–Duhem equation describes the relationship between changes in chemical potential for components in a thermodynamic system: $${\displaystyle \sum _{i=1}^{I}N_{i}\mathrm {d} \mu _{i}=-S\mathrm {d} T+V\mathrm {d} p}$$where See more Deriving the Gibbs–Duhem equation from the fundamental thermodynamic equation is straightforward.
