Given that the standard electrode (E^(@)) of metals are : K^(+)//K=- 2.93 V, Ag^(+)//Ag = 0.80 V, Cu^(2+)//Cu = 0. 34 V, Mg^(2+)//Mg =- 2.37 V, Cr^(3+)// Cr =- 0.74 V, Fe^(2+)//Fe =- 0.44 V . Arrange these metals in an increasing order of their reducing power. Or Two half -reactions of an electrochemical cell are given below : MnO_4^(-) (aq) + 8 H^(+) (aq) + 5 e^(-) rarr Mn^(2+) (aq) + 4 H_(2) O (l) , E^(@) = + 1.51 V, Sn^(2+) (aq) to Sn^(4+) (aq) + 2e^(-) , E^(@) = + 0.15^(V) construct redox equation and predict if the reaction is reactant or product favoured.

Given standard electrode potentials K^(o+)|K=-2.93V, Ag^(o+)|Ag=0.80V , Hg^(2+)|Hg=0.79V Mg^(2+)|Mg=-2.37V,Cr^(3)|Cr=-0.74V Arrange these metals in their increasing order of reducing power.
