1. Define entropy and relate to probability of microstate formation.
2. Relate entropy and reaction spontaneity, Gibbs free energy and reaction spontaneity, and Gibbs free energy and the equilibrium constant of a reaction.
3. Calculate the entropy change within a system and determine absolute entropies.
4. In your own words, define entropy. Provide one everday example resulting in an increase in entropy, and another resulting in a decrease.
1. The entropy of any system, S, is defined as:
S = k*ln(Pmax)
where Pmax is the number of microstates corresponding to the most probable distribution of the system and k is the Boltzmann constant (1.3803 × 10-16 ergs per degree C)
2. The Second Law of Thermodynamics: The entropy of the universe increases for any spontaneous reaction. Applied to a chemical system this means that the entropy of a system can increase or decrease but if it does decrease, then the ...
This solution provides calculations for various calculations for questions regarding entropy.
