Show that the pressure of a written as the sum of "partial pressures" p,, where p, n, rt/v. these "partial pressures" are purely formal quantities not subject to experimental observation. (from the mechanistic viewpoint of kinetic theory the partial pressure p, is the contribution to the total pressure that results from bombardment of the wall by molecules of species i-a distinction that can be made only when the molecules are noninteracting, as in an ideal gas.) multicomponent simple ideal gas can be
