Define and explain Dalton's law of partial pressure.

Answer»

Dalton's law of partial pressure: According to this law, "the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases".

PTotal = P1 + P2 + P3 +…. (At constant T, V) Where PTotal = Total pressures exerted by the mixture of gases. 

P1,P2,Petc. = Partial pressure of gases 

In a mixture of gases, the pressure exerted by the individual gas is called partial pressure.
