Chemistry

A system contains a 0.1 molar solution of NaCl and a 0.01 Msolution of NaCl separated by an oherise impermeable membrane hatcontains a special sodium-conducting pore called an ionophore. The0.1M solution is inside the membane and the 0.01 Molar solution isoutsie the membrane. This ionophore allows free diffusion of theNa+ ions, but not Cl- ions. T=300K, R= 8.31 J/K/mol, F= 96500J/mol/volt...
a) what is the total chemical potential difference, thatincludes concentration dependent potential and electricalpotential, in Joules/mol (outside minus inside) for the sodiumions?
b) considering that chemical potential can have both aconcentration dependent component and an electrical component, whatis the electrical potential, in volts, of the inside of thememebrane with respect to the outside?
c) what is the chemical potential difference in Joule/mol(inside minus outside) for the chloride ions.
