why does the Hydrogen has the different position in electrochemical series than in reactivity series?

Question

chmvijay · Answer

bcoz electrochemical series itself has built by keeping hydrogen electrochemical cell as reference !!!!

you will fo=ind out all your answer.... @chmvijay has a elegant answer

I still can't get it. In the electrochemical series, it represent hydrogen's tendency to release electron. In reactivity series, it represent hydrogen's reactivity, also by releasing electron?

chmvijay · Answer

keeping this constant they have built electrochemical series

anonymous · Answer

the positions are different as both of them are different properties of a molecule or an atom.
