5.1.2 Equilibrium constant Kp Flashcards
1
Q
What is Kp
A
Kp is the equilibrium constant that uses partial pressures
rather than concentration like Kc
2
Q
what is a mole fraction
A
proportion of the mixture
3
Q
How do you work out the mole fraction
A
no. moles/total moles
4
Q
What is partial pressure
A
the contribution of a component of a mixture to the total pressure.
Partial pressure is the pressure it would exert if alone in the box.
5
Q
How is partial pressure worked out
A
partial pressure = mole fraction/ total pressure
6
Q
When is Kp used as opposed to Kc
A
Kp is used for gases whereas Kc is used for gases or aqueous solutions.
7
Q
How is Kp calculated
A
Kp = p(reactants)/p(products)
p() = partial pressure of
