Answer 1

Answer #1

2Br^-(aq) -----------------------> Br2(l) + 2e^- E0 = -1.09v

I2(s) +2e^- -------------------> 2I^- (aq) E⁰ = 0.54v

-----------------------------------------------------------------------------

I₂ (s) + 2Br^- (aq) ---------> 2I^- (aq) + Br₂ (l) E⁰ cell = -0.55v

E⁰ cell = -0.55v

$\Delta$ G⁰ = -nE⁰ cell*F

= -2*-0.55*96500

= 106150J = 1.1*10^5 J >>>>answer

Sulfuric acid is a very strong acid that can act as an oxidizing agent at high...

Sulfuric acid is a very strong acid that can act as an oxidizing agent at high concentrations (very low pH, or even negative pH values). Under standard conditions, sulfuric acid has a low reduction potential, SO42−(aq)+4H+(aq)+2e−⇌SO2(g)+2H2O(l), +0.20 V which means it cannot oxidize any of the halides F2, Cl2, Br2, or I2. If the H+ ion concentration is increased, however, the driving force for the sulfuric acid reduction is also increased according to Le Châtlier's principle. Sulfuric acid cannot oxidize the...
