(a)

Interpretation Introduction

Interpretation:

Thermodynamically stable product compared with reactant in the given reaction has to be determined.

Concept introduction:

Thermodynamic stability can be represented as ΔG0.  Depend upon the value of ΔG0 it is possible to find stability of the product compared with the reactant.

If ΔG0 is negative, then the product is thermodynamically stable compared with the reactant.

If ΔG0 is positive, then the product is thermodynamically unstable compared with the reactant

In an exergonic reaction the products have a lower free energy than it consumes.

In an endergonic reaction the product have a higher free energy than it consumes.

(b)

Interpretation Introduction

Interpretation:

Most kinetically stable product compared with reactant in the given reaction has to be determined.

Concept introduction:

Kinetic stability can be represented as ΔG.  Depend upon the value of ΔG it is possible to find stability of the product compared with the reactant.

If ΔG is large, then the reactant is kinetically stable because it reacts slowly.

If ΔG is small, then the reactant is kinetically unstable because it reacts rapidly.

If ΔG for the reverse reaction is large then he product is kinetically stable, similarly if it is small then the product is kinetically unstable.

In an exergonic reaction the products have a lower free energy than it consumes.

In an endergonic reaction the product have a higher free energy than it consumes.

(c)

Interpretation Introduction

Interpretation:

Least kinetically stable product compared with reactant in the given reaction has to be determined.

Concept introduction:

Kinetic stability can be represented as ΔG.  Depend upon the value of ΔG it is possible to find stability of the product compared with the reactant.

If ΔG is large, then the reactant is kinetically stable because it reacts slowly.

If ΔG is small, then the reactant is kinetically unstable because it reacts rapidly.

If ΔG for the reverse reaction is large then he product is kinetically stable, similarly if it is small then the product is kinetically unstable.

In an exergonic reaction the products have a lower free energy than it consumes.

In an endergonic reaction the product have a higher free energy than it consumes.
