Answer:
= -457.9 kJ and reaction is product favored.
Explanation:
The given reaction is associated with 2 moles of 
Standard free energy change of the reaction () is given as:
, where T represents temperature in kelvin scale
So, 
So, for the reaction of 1.57 moles of , 
As, is negative therefore reaction is product favored under standard condition.
I believe your answer would be A.
I think mm is not a unit of pressure
You are at risk of getting on fire
And all you will hear is fire
Answer:
Explanation:
The first reaction is oxidation of Mn to Mn²⁺ with HNO₃:
(4H⁺ + NO₃⁻ + 3e⁻ → NO + 2H₂O) x2
(Mn → Mn²⁺ + 2e⁻) x3
____________________________________
(1) 3Mn + 8H⁺ + 2NO₃⁻ → 3Mn²⁺ + 2NO + 4H₂O
The oxidation to MnO₄⁻ with IO₄⁻ is:
(2e⁻ + 2H⁺ + IO₄⁻ → IO₃⁻ + H₂O) x5
(Mn²⁺ + 4 H₂O → MnO₄⁻ + 8H⁺ + 5e⁻) x2
_______________________________________
(2) 2Mn²⁺ + 5IO₄⁻ + 3H₂O → 2MnO₄⁻ + 5IO₃⁻ + 6H⁺
