Gibbs'-Dalton's law of partial pressure
The total pressure of a mixture of gases is made up by the sum of the partial pressures of the components in the mixture - also known from Gibbs'-Dalton's Law of Partial Pressures.
- the total pressure exerted by a mixture of gases is the sum of the partial pressures of the individual gases
The total pressure in a mixture of gases can be expressed as:
p = Σpi (1)
p = pressure of mixture (Pa, psi)
pi = partial pressure of individual gas (Pa, psi)
