(a)
Interpretation:
For the given gaseous reaction the entropy
Concept introduction:
Free energy (or) entropy change is the term that is used to explain the total energy content in a
Where,
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. Entropy is represented by the letter ‘S’. It is a state function. The change in entropy gives information about the magnitude and direction of a process. The entropy changes associated with a phase transition reaction can be found by the following equation.
Where,
(b)
Interpretation:
For the given gaseous reaction the free energy
Concept introduction:
Free energy (or) entropy change 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 equation given below helps us to calculate the change in free energy in a system.
Where,
