5.2.2- Enthalpy And Entropy Flashcards
1
Q
What is entropy?
A
A measure of the dispersal of energy in a system which is greater the more disordered a system is
2
Q
When does entropy increase?
A
When temperature increases as particles gain energy
3
Q
What is the equation for free energy?
A
Free energy= enthalpy - temperature * entropy
4
Q
What is the value of free energy if the process is feasible?
A
Negative value
5
Q
Why may a reaction that is thermodynamically feasible still not be able to occur?
A
Due to kinetic factors so the rate is too slow
