Al is used as reducing agent for the extraction of metals such as Chromium,Monganes.Explain why?
Solution) Al3+ + 3 e- <----> Al
Good reducing agents like aluminum have relatively small ionization energies and low electro-negativities by giving up electrons and reducing the elements such as chromium and manganese. So the electrons froms the outer shell of the aluminium atoms simply come out with small energy itself therefore making it effective for reducing many elements.
No, it does not depend upon concentrations of reactants, From the Arrhenius equation, k = Ae^(-Ea/RT) We can say, that it is dependent on activation energy(Ea) and temperatu
