What kind of reaction is KCl plus Na equals NaCl plus K?
This reaction is called a "single displacement" reaction, as the sodium replaces the potassium in combination with the chlorine. *This is the high-temperature distillation reaction to produce metallic potassium, and is not a spontaneous reaction because potassium is more reactive than sodium. The corresponding single replacement reaction is K + NaCl => Na + KCl.
