The potential in an electrochemical cell, E, is related to the Gibb's free energy change (ΔG) for the overall cell redox reactio
Nana76 [90]

Answer:

Explanation:

As an example, the following cell reaction: Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(m) generates a cell voltage of +1.10 V under standard conditions. Calculate and enter delta G degree (with 3 sig figs) for this reaction in kJ/mol.

Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(m)

ΔG = ΔG° + RTInQ

Q = 1

ΔG = ΔG°

ΔG = =nFE°

n=no of electrons transfered.

E° = 1.1v

ΔG° = -2 * 96500 * 1.10

= -212300J

ΔG° =-212.3kJ/mol

<h3>Therefore, the ΔG° = -212.3kJ/mol</h3>

g Ammonium nitrate was the oxidizing agent used that damaged the New York World Trade Center in 1993 and the Federal Building in
Cloud [144]

Answer:  51.3\times 10^3 kJ

Explanation:

The thermochemical equation for decomposition of ammonium nitrate is:

NH_4NO_3(s)\rightarrow N_2O(g)+2H_2O(g)   \Delta H=-82.1kJ

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass= 50.0 kg =50.0\times 10^3g   (1kg=1000g)

\text{Number of moles of ammonium nitrate}=\frac{50.0\times 10^3g}{80g/mol}=0.625\times 10^3moles

According to stoichiometry:

1 mole of NH_4NO_3 gives = 82.1 kJ of heat

Thus 0.625\times 10^3moles of NH_4NO_3 give =\frac{82.1}{1}\times 0.625\times 10^3=51.3\times 10^3  kJ of heat

Thus 51.3\times 10^3 kJ of heat is evolved from the decomposition of 50.0 kg of ammonium nitrate.
