Question

Chem

Calculate Eo for each of the following reactions, and tell which are spontaneous under standard-state conditions. 5Ag+(aq) + Mn2+(aq) + 4H2O(l) rightarrow 5Ag(s) + MnO-4 (aq) + 8H+(aq) Express your answer using two decimal places. 2H2O2(aq) rightarrow O2(g) + 2H2O(l) Express your answer using two decimal places. Calculate Eo for each of the following reactions, and tell which are spontaneous under standard-state conditions. Tell which are spontaneous under standard-state conditions. Check all that apply.

Explanation / Answer

Part A. E= (114/50)*5 =1.14

Part B. E= (68/36)=1.8889

Part C. Second reaction will be spontaneous because mg can act as self oxidising agent under standard state conditions.
