Chemical Equilibria Flashcards
(6 cards)
1
Q
Steady State
A
System which is unchanging at the visible and molecular levels
Ex. 2NaCl-> Na + Cl2
2
Q
Dynamic Equilibrium
A
System which is unchanging at the visible level, but has constant change
3
Q
Characteristics of equilibrium system
A
- closed system-no substance can enter or leave reaction(if gas lid must be opened so gas can escape)
- Aqueous substances and gases only
- Liquids & solids have no effect on the system
- Catalysts speed up both forward and reverse reaction.equilibrium is reached quicker but not affected
4
Q
Concentration
A
[ ] [ ]
5
Q
Graphs: where is equilibrium reached? What’s favoured p’s or r’s
A
At the point where they are both parallel to each other
6
Q
Haber Process??????
A
Industrial process for making ammonia from nitrogen and hydrogen. Important in making explosives & fertilizers
