Is there any difference between the intensive properties of saturated vapor at a given temperature and the vapor of standard mixture at same temperature?

Yes, there is a difference between the intensive properties of saturated vapor and the vapor of a standard mixture at the same temperature. Saturated vapor is in equilibrium with its liquid phase and possesses specific properties such as pressure and enthalpy that are defined by the saturation conditions. In contrast, the vapor of a standard mixture may contain different components and concentrations, resulting in varied intensive properties like density, specific heat, and chemical potential, even at the same temperature. Thus, while they may share a temperature, their thermodynamic characteristics can be distinctly different.
