Two half-reactions of an electrochemical cell are given below :MnO–4 (aq) + 8H+ (aq) + 5e– → Mn2+ (aq) + 4H2O (I), E° = 1.51 VSn2+ (aq) → Sn4+ (aq) + 2e–, E° = + 0.15 V.Construct the redox reaction equation from the two half-reactions and calculate the cell potential from the standard p...

Two half-reactions of an electrochemical cell are given below :

MnO–4 (aq) + 8H+ (aq) + 5e– → Mn2+ (aq) + 4H2O (I), E° = 1.51 V

Sn2+ (aq) → Sn4+ (aq) + 2e–, E° = + 0.15 V.

Construct the redox reaction equation from the two half-reactions and calculate the cell potential from the standard potentials and predict if the reaction is reactant or product favoured.

The following reaction should take place: Z n + H 2 S O 4 Z n S O 4 + H 2

Std. EMF of the cell ( E c e l l ) = [ Std. redn. pot. of R.H.S. electrode ] [ Std. redn. pot. of L.H.S. electrode ] = 0 ( 0.76 ) = + 0.76

Thus, the EMF of the cell comes out to be positive. hence, the reaction takes place.
