What is the Dalton law of partial pressure equation?
Dalton's law of partial pressures states that in a gaseous mixture, the pressure exerted by a component is the same as if that component ALONE occupied the container..........
......The total pressure is the sum of the individual partial pressures.
So we have a gaseous mixture of gases
Reasonably we can idealize gas behaviour, i.e.
We can thus say that the partial pressure of a gas in a gaseous mixture is proportional to its mole fraction.
