(d) Let S1 2 (NA) denote the component of entropy reflecting the distribution of NA molecules in compartment A. Assuming that NI >> 1 and Na >> 1 show that changes in Sit-2 (NA) during molecular exchanges of species 1 with compartment B is given by; as1+2 (NA) ONA 8 -k In xA where k denotes a constant and of the partial molecular fraction of species 1 is defined so; Ni x1 NA+ Na Hint: The membrane is permeable to only molecular species 1.
