The reaction type should be identified given sulfur formation reaction. Concept Introduction: Disproportionation reaction: These are a special type of reaction where an element in one oxidation state is simultaneously oxidized and reduced. One of the reacting substance in a disproportionation reaction always contains an element that can exist in at least oxidation state. The element in the form of reacting substance is in the intermediate oxidation state.

Solution Summary: The author explains that the reaction type should be identified given sulfur formation reaction.
Definition Definition Chemical reactions involving both oxidation and reduction processes. During a redox reaction, electron transfer takes place in such a way that one chemical compound gets reduced and the other gets oxidized.

(a)
Interpretation Introduction
Interpretation:
The reaction type should be identified given sulfur formation reaction.

Interpretation Introduction
Interpretation:
The equilibrium constant Kp value should be derived given the redox reaction at 25°C.
Concept Introduction:
Free energy: is the term that is used to explain the total energy content in a thermodynamic system that can be converted into work. The free energy is represented by the letter G. All spontaneous process is associated with the decrease of free energy in the system. The free energy change (ΔGrxn) is the difference in free energy of the reactants and products in their standard state.
It should be determine that given sulfur dioxide deposits reaction more or less effective at a higher temperature.
Concept Introduction:
Free energy (Gibbs free energy) is the term that is used to explain the total energy content in a thermodynamic system that can be converted into work. The free energy is represented by the letter G. All spontaneous process is associated with the decrease of free energy in the system. The standard free energy change (ΔG°rxn) is the difference in free energy of the reactants and products in their standard state.

Write the reagents required to bring about each reaction next to the arrows shown.
Next, record any regiochemistry or stereochemistry considerations relevant to the
reaction. You should also record any key aspects of the mechanism, such as forma-
tion of an important intermediate, as a helpful reminder. You may want to keep
track of all reactions that make carbon-carbon bonds, because these help you build
large molecules from smaller fragments. This especially applies to the reactions in…
