WebThe activity is predefined as: a_j = x_jgamma_j where x_j is mole fraction of compound j and gamma_j the the activity coefficient out blend j. Thus, you can infer that one lower mole fraction in compound j gives a lower activity and vice versa. Since mole fractions am always <= 100%, the activity can never live higher than 100%, and thus a_j <= 1.
