U2|Equilibrium 9-12 Flashcards
1
Q
when a substance is added (increase in concentration)
A
equilibrium shifts to consume it
2
Q
when a substance is removed (decrease in concentration)
A
equilibrium shifts to produce it
3
Q
when solids or liquids are added
A
these DO NOT impose change (these components don’t appear in Q or K expressions)
4
Q
addition of an inert gas
A
- it will have no effect as long as the volume stays constant
- consider while that total pressure increases, the partial pressures don’t change (ratio does not change)
5
Q
lower pressure and increase volume
A
- equilibrium shifts to increase the total number of gas molecules
6
Q
higher pressure and decrease volume
A
- decrease total number of as molecules
7
Q
increase in temperature
A
- equilibrium shifts to “consume” heat, think of it as a reactant
8
Q
decrease in temperature
A
- equilibrium shifts to “produce” heat, think of it as a reactant
9
Q
the more product, the higher the K value
A
