Question

define daltan's law of pressure

Answer 1

In chemistry and physics, Dalton's law (also called Dalton's law of partial pressures) states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.

Answer 2

Mathematically, the pressure of a mixture of non-reactive gases can be defined as the summation:

{\displaystyle p_{\text{total}}=\sum _{i=1}^{n}p_{i}} {\displaystyle p_{\text{total}}=\sum _{i=1}^{n}p_{i}} or {\displaystyle p_{\text{total}}=p_{1}+p_{2}+p_{3}+\cdots +p_{n}} {\displaystyle p_{\text{total}}=p_{1}+p_{2}+p_{3}+\cdots +p_{n}}

where p1, p2, ..., pn represent the partial pressures of each component.[1]

{\displaystyle p_{i}=p_{\text{total}}x_{i}} {\displaystyle p_{i}=p_{\text{total}}x_{i}}

where xi is the mole fraction of the ith component in the total mixture of n components.
