Question

Two half cell reactions of an electrochemical cell are given below :
MnO–4(aq) + 8H+ (aq) + 5e– → Mn2+ (aq) + 4H2O (I), E° = + 1.51 V
Sn2+ (aq) → 4 Sn4+ (aq) + 2e–, E° = + 0.15 V
Construct the redox equation from the two half cell reactions and predict if this reaction favours formation of reactants or product shown in the equation...​

Answer 1

The reactions can be represented at anode and at cathode in the following ways :

At anode (oxidation) :

Sn2+ → = Sn4+ (aq) + 2e– ] × 5 E° = + 0.15 V

At cathode (reduction) :

MnO–4(aq) + 8H+ (aq) + 5e– → Mn2+ (aq) + 4H2O (I)] × 2 E° = + 1.51 V

The Net R × M = 2MnO–4(aq) + 16H+ + 5Sn2+ → 2Mn2+ + 5Sn4+ + 8H2O

Now E°cell = E°cathode – E°anode

= 1.51 – 0.15 = + 1.36 V

∴ Positive value of E°cell favours formation of product.

Explanation:

Why is the poem the spider and the fly called a fable?

Fable is a poem or a story that consist any moral and characters of that poem or story should be animals. This poem is called a fable because its is a poem from a great humor 'Marry jjjjHowitt', the animals like spider and fly are characters and it also gives moral.
