Kp Flashcards
1
Q
partial pressure
A
The partial pressure of a gas in a mixture is the pressure that the gas would have if it alone occupied the volume occupied by the whole mixture.
2
Q
partial pressure formula
A
mole fraction x total pressure
3
Q
mole fraction
A
gas 1 / all gases moles
4
Q
expression
A
p (NH3) 2 etc etc
5
Q
unit
A
Pa
6
Q
change in Kp
A
They do not change if pressure or concentration are altered.
A catalyst also has no effect
7
Q
effect of temp
A
If temperature is increased the reaction will shift to oppose the change and move in the backwards endothermic direction. The position of equilibrium shifts left. The value of Kp gets smaller as there are fewer products.
