Q
Enthalpy
What are most of these reactions?
What is the direction?
A
Exothermic
High to low
1
Q
What is a spontaneous change?
If one way is spontaneous can the reverse be?What does feasible mean?
A
A reaction that occurs without being driven by an external influence
No
Can happen not will happen
2
Q
Entropy What is the symbol for it? What is the direction? What have lower entropy? What change in state does it increase with?
A
S
Lower to higher
Simpler molecules
Solid to liquid to gas
3
Q
What does entropy increase with?
A
Temp
4
Q
What is ^G? What is the equation to work out ^G? Therefore it is what dependent? What does the result have to be to mean a reaction is feasible? How do you work out temp?
A
Gibs free energy ^G= ^H-T^S Temperature Equal to or less than 0 T=^H/^S
