For question 1:
<span>25°C = 298 K
</span><span>ΔG = ΔH - T ΔS
</span>ΔH= ΔG + TΔS = −91368 + (298)(−284)=−91368-84632=-175730
<span>Therefore ΔH is approx - 176,000 J
</span>
For question 2:
The statement "A negative change in free energy, or −ΔG, represents a spontaneous reaction." is false
An ionic bond. covalent bonds do not conduct in a solid or a liquid state, ionic bonds conduct in a liquid state and not in a solid state.

<u>Answer:</u> The standard electrode potential of the cell is 0.62 V.
<u>Explanation:</u>
For the given chemical equation:
The substance having highest positive potential will always get reduced and will undergo reduction reaction.
<u>Oxidation half reaction:</u> ( × 3 )
<u>Reduction half reaction:</u> ( × 2 )
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
To calculate the of the reaction, we use the equation:
Hence, the standard electrode potential of the cell is 0.62 V.
