14. Chemical Equilibrium Flashcards
(9 cards)
1
Q
Concentration soft products and reactants no longer change - rates of forward and reverse reactions are equal
A
Equilibrium
2
Q
Forward and reverse reactions continue to occur, but they occur at the same rate, so no net change is observed
A
Dynamic state of chemical equilibrium
3
Q
Characteristics of equilibrium (3 pt)
A
- dynamic and reversible (conc not equal but rates are equal)
- macroscopic properties of stem are not changing
- characterized by ratio of 2 rate constants (gives eq constant, k..c)
4
Q
Ratio of product concentrations to reactant concentrations at any moment of a reaction
A
Reaction quotient (Q)
5
Q
When a system at equilibrium is subjected to change, the system responds to re-establish equilibrium
A
Le Chatelier’s Principle
6
Q
Effect of temp increase on Kc
A
Increase
7
Q
Effect of temp decrease on Kc
A
Decrease
8
Q
Effect of pressure change on Kc
A
No change
9
Q
Effect of catalyst on Kc
A
No change
