Flashcards in 19.2 the equilibrium constant Kp Deck (9):
What is a mole fraction?
The proportion by volume of a gas to the total volume of the gases in a mixture
What is the sum of the mole fractions in a mixture?
What is partial pressure?
The contribution that a gas makes towards the total pressure
What is the sum of the partial pressures?
The total pressure
What is the amount of oxygen that can dissolve in blood proportional to?
The partial pressure of the oxygen breathed in
What happens as oxygen dissolves in blood?
It combines with haemoglobin allowing much more to dissolve
What happens to the oxygen dissolving in blood at high altitudes?
The body will produce more haemoglobin but the partial pressure of oxygen may be so small that little will dissolve therefore people use oxygen tanks with pure oxygen in
What are the units for partial pressure?
kPa, Pa or atm (same should be used for all gases)
