Entropy and Feasibility of Reactions (3.7) Flashcards
1
Q
Entropy
A
The degree of freedom of a system
2
Q
Calculation for Standard entropy
A
ΔS=S(products)-S(reactants)
3
Q
Second Law of Thermodynamics
A
Entropy will always tend to increase in any isolated system that is not in equilibrium.
4
Q
Gibbs free energy
A
ΔG=ΔH−TΔS
If energy change is negative reaction will occur spontaneously.
5
Q
Formula to calculate minimum temperature the reaction is feasible at:
A
T=ΔH/ΔS
