Equilibrium Flashcards
If /\H is -, is it endo or exo?
Exothermic
If /\H is +, is it endo or exo?
Endothermic
How does temperature increase affect Kp?
Endothermic = kp increases
Exothermic = kp decreases
How does pressure affect Kp?
It doesn’t - stays the same
How does a catalyst affect Kp?
It doesn’t - stays the same
How does temperature increase affect amount of product at equilibrium?
Exothermic - decreases
Endothermic- increase
How does pressure affect amount of product at equilibrium?
More in reactants = amount increase amount of product
More in products = decrease amount of product
How does a catalysts affect amount at equilibrium?
Doesn’t - stays the same
How does increasing temperature affect initial rate?
Exothermic- increases
Endothermic - decreases
How does increasing pressure affect initial rate?
More in reactants - increases rate
More in products - decrease rate
How does a catalyst affect initial rate?
Increase rate
What are some features of a dynamic equilibrium?
- Exists in a closed system
- Forwards reaction = backwards reaction
- Concentration, pressure and temperature remain constant
