Answer:
ΔG° = 2.57 × 10² kJ
The reaction is spontaneous.
Explanation:
<em>The standard cell potential, E°cell, for a reaction in which two electrons are transferred between the reactants is +1.33 V. Calculate the standard free energy change, ΔG°, in kJ for this reaction and determine if it is spontaneous or nonspontaneous at 25°C.</em>
<em />
We can calculate the standard Gibbs free energy (ΔG°) using the following expression.
ΔG° = -n × F × E°cell
where,
n: moles of electrons transferred
F: Faraday's constant
E°cell: standard cell potential
ΔG° = - (2 mol) × (96468 J/V . mol) × 1.33 V
ΔG° = -2.57 × 10⁵ J = 2.57 × 10² kJ
ΔG° < 0 means that the reaction is spontaneous.

Phase of matter
Explanation:
The phase of matter strictly is a function of its temperature. Matter exists in different phases at different temperatures.
- Matter is anything that has weight and occupies space.
- There are three states of matter:
- Solid
- Liquid
- Gas
These phases of matter depends on temperature.
For example;
- Water exists as gases above boiling point
- Water is also solid at freezing point.
- Between the freezing and boiling point, water is a liquid.

Answer:
The most stable conformation of the following compound has
A. An axial methyl group and an axial ethyl group.
B. An axial methyl group and an equatorial ethyl group.
C. An axial tert-butyl group.
D. An equatorial methyl group and an equatorial ethyl group.
E. An equatorial methyl group and an axial ethyl group.
Explanation:
The most stable conformation in the cyclohexane ring is the one in which both the substituents are in the equatorial position.
Among the given options,
option D An equatorial methyl group and an equatorial ethyl group.
When the substituents in the cyclohexane ring are in equatorial positions then, the steric repulsions will be reduced.
Answer is option D.
