# How would you explain partial pressure?

Feb 18, 2017

$\text{The partial pressure is the pressure exerted....}$

#### Explanation:

$\text{The partial pressure is the pressure exerted by a component, A,}$
$\text{in a gaseous mixture. " P_A" is the same as the pressure it would}$ $\text{exert if it ALONE occupied the container.}$

And thus ${P}_{\text{total}} = {P}_{A} + {P}_{B} + {P}_{C} \ldots \ldots \ldots$

If we assume ideality, then P_"Total"=(n_"Total"RT)/V

$= \left({n}_{1} + {n}_{2} + {n}_{3.} \ldots .\right) \times \frac{R T}{V}$

And thus the $\text{partial pressure}$ is proportional to its molar quantity.
