Vapour pressure

    If the vapour pressure of a component is bigger than the system pressure, does it means it will fully in vapour phase and no liquid phase are formed??

    Yes, or if a liquid phase was already existing then it will begin to boil away.

    the moment the partial pressure of a component is equal to its vapor pressure, any additional mass of that component formed must be in the vapor phase (and no longer in the liquid phase).
