How can constraints be used to help define the problem?
vitfil [10]

Answer:

Constraints are restrictions that need to be placed upon variables 

Explanation:

Constraints are restrictions (limitations, boundaries) that need to be placed upon variables used in equations that model real-world situations. It is possible that certain solutions which make an equation true mathematically, may not make any sense in the context of a real-world word problem.

Part a the disproportionation of mn2+(aq) to mn(s) and mno2(s) in acid solution at 25 ∘c. calculate δg∘rxn.
ollegr [7]

Answer:

ΔG^{o} = -461198.3 J

Explanation:

Gibbs free energy is defined as the energy associated with a given chemical reaction which can be used to do work. Firstly, we need to figure out the chemical equation for the given problem. For the given problem, the chemical equation is:

Mn^{2+} _{(aq)} + 2e^{-}⇒Mn_{(s)}      E^{o} = -1.18 V

Mn^{2+} _{(aq)} + H_{2}O ⇒MnO_{2(s)} +4H^{+} + 2e^{-}E^{o} = -1.21 V

The addition of the two E^{o} gives the E_{cell} of the equation, i.e. -1.18-1.21 = -2.39 V.

Then, using the equation for ΔG^{o}, we have:

ΔG^{o} = n*F*E^{o} = 2*96485*-2.39 = -461198.3 J
