What is the units of pressure in Antoine equation?

The Antoine correlation as presented in equation 8 yields vapor pressure in units of mmHg. The Antoine constants A and B are dependent upon the units of pressure (mmHg or bar) and to the logarithmic function that is employed (natural logarithm or base-10 logarithm).

Is Antoine equation accurate?

The Antoine equation is a semi-empirical equation which expresses vapour pressure as a function of temperature. A, new, rapid and highly accurate method for obtaining its three constants from experimental data is presented and applied to ethanol, water and 14 anaesthetic substances.

How do I calculate saturation pressure?

Take the temperature of the system for which you want to determine saturation pressure. Record the temperature in degrees Celsius. Add 273 to the degrees Celsius to convert the temperature to Kelvins. Calculate saturation pressure using the Clausius-Clapeyron equation.

Does Antoine equation use Celsius or Kelvin?

It is relatively easy to convert the Antoine coefficients based on using Celsius scale temperatures to make them suitable for using Kelvin scale temperatures. All that is required is to subtract 273.15 from the C coefficient….[edit] Units.

What does the Clausius-Clapeyron equation represent?

The Clapeyron equation (also called the Clausius-Clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.

How do you calculate saturated vapor concentration?

Calculating Vapor Concentration The equations that can be used are; To find the percent (%) concentration for a material multiply the vapor pressure of the material in mm/Hg by 100 and divide by 760.
