11.3 - Gaseous Equilibrium

• what's partial pressure?

  a measure of the concentration of a gas in a mixture

  the pressure a gas would exert if it was th only gas present in a container
• what's total pressure?

  sum of all partial pressures of a gas mixture
• what's mole fraction?

  proportion of gas mixture that is a particular gas
• what's the sum of mole fractions equal to?

  1
• equation for the mole fraction of a gas?

  number of moles of gas / total number of moles
• equation for partial pressure of a gas

  mole fraction of a gas x total pressure
• dalton's law of partial pressure

  total pressure of a mixture of gases is equal to the sum of the partial pressures
