Is Potassium More Reactive Than Lithium? A Look at the Electrochemical Series

[jsmith613]

The electrochemical series:
http://www.chemguide.co.uk/physical/redoxeqia/ecs.html#top
ranks Li above K
but potassium is more reactive than lithium
given that Lithium gives up electrons more easily according to the electrochemical series, how can this be?

 

[Borek]

potassium is more reactive than lithium

Define "more reactive".

 

[jsmith613]

Define "more reactive".

will displace it from its compound
so K will displace Li from LiCl

 

[Borek]

so K will displace Li from LiCl

Will it? Even if, standard potentials are for standard conditions (activity of everything equal 1). Reacting two solids has nothing to do with standard conditions.

Can you provide a reference for your claim. I tried Googling it and kind find any reference to Potassium displacing Lithium from LiCl.
