Interpreting BET analysis data involves understanding the BET plot and parameters: 1. Linear Region: The linear portion of the BET plot is used to calculate the specific surface area. 2. Slope and Intercept: The slope and intercept of the BET plot are used to derive the BET constant (C) and the monolayer capacity (V_m). 3. Surface Area Calculation: The specific surface area is calculated using the monolayer capacity and the known cross-sectional area of the adsorbate molecule (usually nitrogen).
