Equilibrium Flashcards
(9 cards)
1
Q
What is Henry’s law
A
The mass of a gas dissolved in a solvent in proportional to the pressure if the gas above the solvent.
2
Q
Charactersitics of equilibria
A
- Closed system
- Dynamic in nature
- measurable properties become contsnat
- expression for C which is contant at constant temp
- magnitude of constentration expression gives the indication of the extent of the reaciton
3
Q
Desrcube the state of quiliburbrum
A
The state where the measurable properties of a system such as concentration does not undergo any further change
4
Q
Law of mass action
A
The rate os a reaction is proportional to the product of contentrations raised to their stoichometric coefficients
5
Q
Law of chemical equilibrium
A
at given temp, ratio of forward and backward rate is constant
6
Q
Types of equilibrium
A
- Homogenous equilibrium - same state
- hetorgenous equilibrium - different states
7
Q
What happens when Q and K differ
A
- Q>K : backward
- Q<K : forward
8
Q
Le chatelier’s principle
A
If a system in equilibrium is subjected a stress, the equilibrium will shift such as to undo the effect of the stress
