Electronegativity vs electrochemical series

Carbon is higher in the electrochemical series than hydrogen, which indicates it is more electropositive, but Pauling values show carbon as more electronegative - 2.55 vs 2.2!!?

Any reason / explanation for the apparent contradiction? Tried looking for an Eo value for C (should be more negative then -0.76V) but no joy ...

Come to that, Li is less reactive than K, but has a greater Eo ...

Thanks in advance for any replies

This is comparing apples and oranges. There exist some slight correlation, but these are separate scales.
