Chapter 19 (Equilibrium Constant) Flashcards
1
Q
How is mole fraction found?
A
Number of moles of a gas / total number of moles of all gas
2
Q
How is partial pressure found?
A
Mole fraction x total pressure of gas
3
Q
What factor changes Kp?
A
Temperature
4
Q
What happens to Kp if pressure is changed?
A
Will move to oppose the change.
If pressure increases then equilibrium shifts to the side with less fewer moles of gas.
5
Q
What happens to Kp if temperature is changed?
A
Will move to oppose the change.
If temperature increases then equilibrium will shift to endothermic side to oppose the change and decrease the temperature.
6
Q
What unit is Kp measured in?
A
pa or Kpa
7
Q
What is a heterogenous reaction?
A
Substances are in different phases.
8
Q
What is a homogenous reaction?
A
All substances are in same phase.
