Interpretation:
The change in entropy in the given reaction has to be determined
Concept Introduction:
Entropy is a
During a phase transition, if the solid state is changed to liquid state or gaseous state there will be an in increase in entropy in the system. The solid state is having more orderly arrangement than the liquid and gaseous state. Gaseous state, having more possible arrangements of atoms will have the highest order of entropy.
(b)
Interpretation:
The change in entropy in the given reaction has to be determined
Concept Introduction:
Entropy is a thermodynamic quantity, which is the measure of randomness in a system. The term entropy is useful in explaining the spontaneity of a process. For all spontaneous process in an isolated system there will be an increase in entropy. Let us consider the example of diffusion of gas molecule to understand the concept of entropy. When a perfume bottle is opened the fragrance is immediately spread into the surroundings. Inside the bottle the gas molecules are close to each other and entropy is less. Once the bottle is opened the gas molecules escapes into the surroundings and have more disorderly arrangements.
