Solution Summary: The author explains that a balanced chemical equation for the reaction needs to be determined. The entropy is defined as randomness in the system.
Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.

Interpretation Introduction
(a)
Interpretation:
A balanced chemical equation for the reaction needs to be determined.
Concept introduction:
A chemical reaction is said to be balanced, if there are equal number of atoms of same elements on both sides of the reaction arrow.
Interpretation Introduction
(b)
Interpretation:
The sign of ΔH and ΔS for the above reaction needs to be determined.
Concept introduction:
The entropy is defined as randomness in the system. For a system with more gaseous species, the randomness is more as compared to liquid and solid species.
For an exothermic reaction, the sign of ΔH is negative and for endothermic reaction it is positive.
Interpretation Introduction
(c)
Interpretation:
Whether the reaction is spontaneous at low temperature, high temperature or at all temperatures needs to be explained.
Concept introduction:
The relation between change in enthalpy, change in Gibbs free energy and change in entropy is represented as follows:
ΔG=ΔH−TΔS
Here, ΔG is change in Gibbs free energy, ΔH is change in enthalpy, T is temperature and ΔS is change in entropy.
