Effects Of Conditions On Equilibrium Constants kp And Kc Flashcards
What happens to K for exothermic reactions
Increase in temp
Decrease in temp
K decreases
K increases
What happens to K for endothermic reactions
Increase in temp
Decrease in temp
K increases
K decreases
If pressure increases what happens to partial pressure of reactants
It doubles
An increase in pressure does what to the equilibriumm yield and what to the equilibrium position
Increases the equilibrium yield and shifts position right
A decrease in pressure does what to the equilibriumm yield and what to the equilibrium position
Decreases the equilibrium yield
Positions shifts left
If pressure increases what happens to Qc
And why
It is 1/4 of Kp
Due to reactants producing more products
Effect of catalyst on constant and position
Why
No effect on constant or position
Doesn’t appear in equations
When the concentration of one of the components of a equilibrium mixture is altered there is an immediate change in the
Reaction quote
Qc
What is Qc
The relationship between the concentrations of the components
What is Qcs equation
The ame as Kc
If there is a change in concentration what happens to Qc and how does this change
Qc no longer equals Kc
The equilibrium will change until Qc=Kc
