The formula to calculate the pressure using the Antoine equation is:
\[ \text{P} = 10^{\left(A - \frac{B}{C + T}\right)} \]
Where:
The Antoine equation is a mathematical expression used to calculate the vapor pressure of pure substances. It relates the vapor pressure to temperature and is widely used in chemical engineering and thermodynamics. The equation is particularly useful for predicting the boiling points of liquids under different pressures.
Let's consider an example:
Using the formula to calculate the pressure:
\[ \text{P} = 10^{\left(8.07131 - \frac{1730.63}{233.426 + 25}\right)} \approx 23.69 \text{ Pa} \]
This means that the pressure for this scenario is approximately 23.69 Pa.
