How are the concentrations at gaseous equilibrium expressed?

Partial pressure

2
New cards

Partial pressure

The pressure that the gas would exert if it occupied the container on its own

3
New cards

Formula for partial pressure

mole fraction x total pressure

4
New cards

Mole fraction formula

Number of moles of gas A in mixture / total number of moles of gas in mixture

5
New cards

What is the symbol for the equilibrium constant for gaseous equilibria?

Kp

6
New cards

Give the formula for Kp for the following reaction at equilibria:
A + B -> C + D

Kp = (pC)(pD) / (pA)(pB)

7
New cards

How does Le Chatelier's principle affect gaseous equilibria?

The same way as it effects equilibria in solution

8
New cards

What changes the value of Kp?

Temperature
