Volume of Monolayer Gas by BET Equation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Monolayer Volume of Gas = ((Vapour Pressure-(Vapour Pressure/Saturated Vapor Pressure of Gas))*(1+(Adsorbent Constant*(Vapour Pressure/Saturated Vapor Pressure of Gas)))-(Vapour Pressure/Saturated Vapor Pressure of Gas)*Total Equilibrium Volume of Gas)/(Adsorbent Constant*(Vapour Pressure/Saturated Vapor Pressure of Gas))
V_mono = ((P_v-(P_v/P₀))*(1+(C*(P_v/P₀)))-(P_v/P₀)*V_total)/(C*(P_v/P₀))
This formula uses 5 Variables

Variables Used

Monolayer Volume of Gas - (Measured in Cubic Meter) - The Monolayer Volume of Gas is the volume required to cover the unit mass of adsorbent with unimolecular layer.
Vapour Pressure - (Measured in Pascal) - The Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature.
Saturated Vapor Pressure of Gas - (Measured in Pascal) - The Saturated Vapor Pressure of Gas is standard vapour pressure at a, particularly given temperature.

What is BET theory?

The BET theory (abbreviated from Brunner-Emmett-Teller theory) is used to measure the surface area of solid or porous materials. It gives important information on their physical structure as the area of a material’s surface affects how that solid will interact with its environment. Many properties such as dissolution rates, catalytic activity, moisture retention, and shelf life are often correlated to a material’s surface area. Critical to the design and manufacture of solids, surface area analysis is one of the most widely used methods in material characterization. This article gives insight into the procedure of BET surface analysis and its application in industry.
