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

A 0.5 mol sample of he(g) of ne(g) are placed separately in two 10.0 l rigid containers at 25°c. each container has a pinhole op
Serjik [45]
The movement of gases through pinhole is called effusion and the effusion rate indirectly proportional to the molar mass of gas

The lighter mass gas effuses faster than the heavier one
so He(g) will escapes faster and it will move with higher average speed because it has less mass than Ne(g)

given two equations representing reactions: which type of reaction is represented by each of these equations?
Sergeeva-Olga [200]

Answer:

Equation 1 - nuclear fission

Equation 2 - nuclear fusion

Explanation:

Nuclear fission is a reaction in which a large nucleus is split into smaller nuclei when it is bombarded by neutrons. The process produces more neutrons to continue the chain reaction. This is clearly depicted in equation 1 as shown in the question.

Nuclear fusion is a reaction in which two light nuclei combine in order to form a larger nuclei. This is clearly depicted in equation 2 as shown in the question.
