The entropy (S) for one mole of crystalline N₂O at 0 K is 3.28 × 10⁻²² J/K.
What is Entropy (S) ?
- The quantity of thermal energy per unit of temperature in a system that cannot be utilized to carry out meaningful work is termed as entropy.
- It is denoted by S.
- Since work is generated by ordered molecular movement, entropy also acts as a substitute for a system's molecular disorder or unpredictability.
- Entropy theory offers deep insights into how frequently common events spontaneously change.
- Boltzmann's entropy formula that gives the relation between the absolute entropy S of a thermodynamic system and the number of possible microstates is given as follows :
S = k logW , Where K is Boltzmann's constant.
From the given question,
S = (1.38 × 10⁻²³) (6.022 × 10⁻²²)
S = 3.28 × 10⁻²² J/K
