How are the concentrations at gaseous equilibrium expressed?
Partial pressure
Partial pressure
The pressure that the gas would exert if it occupied the container on its own
Formula for partial pressure
mole fraction x total pressure
Mole fraction formula
Number of moles of gas A in mixture / total number of moles of gas in mixture
What is the symbol for the equilibrium constant for gaseous equilibria?
Kp
Give the formula for Kp for the following reaction at equilibria:
A + B -> C + D
Kp = (pC)(pD) / (pA)(pB)
How does Le Chatelier's principle affect gaseous equilibria?
The same way as it effects equilibria in solution
What changes the value of Kp?
Temperature
