reactivity series

hey guys,
i was wondering why the voltage of a galvanic cell increased when the two metals are further apart in the series.
cheers

voltage is a measurement of energy of the electron. 1V = 1.6E-10 J per electron, which is equivalent to 96.5 kJ/mol of electron. Therefore, you can see that voltage essentially describes

When the reacting species are spaced further apart, it simply means they have a larger , i.e. more energy is released. We use the electrochemical series to determine whether or not the reaction will give us a negative (if energy will be released). Spontaneous reactions typically have a negative .

ye but y and how is it got to do with the electronegative ? plz reply

It's got nothing to do with electronegativity. When two reactants are further apart, they are stronger oxidants/reductants, and react to form weaker oxidant/reductants. I.e. more unstable reactant --> more stable products. Draw the energy diagram, you'll find that is larger. Reaction releases more energy, thus greater voltage.

Electronegative is not negative voltage, I think you got those mixed together
