Question

Explain Dalton's Law of partial pressures..​

Answer 1

$\huge\bold{Answer}$

$\bold{Dalton's\: Law\: of\: partial\: pressures}$

__________________________________________

»»» This law was formulated by $\small\bold{John\: Dalton}$.

This law states that,

The total pressure exerted by a mixture of two or more non - reacting gases in a definite volume is equal to the sum of the individual pressures which each gas would exert if it occupies the same volume alone at a constant temperature.

For e.g.

if p1, p2, p3... are individual pressure of gases known as partial pressures, then the total pressure p(total) of the mixture of gases at the same temperature is given by the relation

p(total) = p1 + p2 + p3 + ....

Answer 2

Answer:

According to it at constant temperature and volume, total pressure of gaseous component is a sum of partial pressure of each component.

OR

When we mix two or more non reactive gases in same vessel, then total pressure is the sum of partial vapour pressure of each component at constant temperature and volume.
