Why does the molar conductivity (Λₘ) of an electrolyte increase while its conductivity (κ) decrease with a decrease in concentration (or with an increase in dilution)? It's really counterintuitive. Don't they both imply somthing similar? If yes, how can they show completely opposite behaviour in this case?
As per Wikipedia, Λₘ increases due to a decrease in solute–solute interaction. I would like to have an elaborative explanation for this. A decrease in κ (in case of a strong electrolyte) upon dilution can be clearly understood by the fact that there is a decrease in number of ions per unit volume. But the fact that there is an increase in Λₘ upon dilution is just too counterintuitive for me and thus I can't shove this fact down my throat. A lesser math ridden and a more mechanism based answer would be highly appreciated.
