To determine the specific surface area of the sample based on the BET model, we need to follow these steps:1. Convert the pressure data to relative pressure P/P0 by dividing the pressure values by the saturation pressure of nitrogen at the experimental temperature. For simplicity, we will assume P0 = 760 torr 1 atm .Relative Pressure P/P0 | Volume of nitrogen cm3 -------------------------|----------------------- 50/760 | 24.51 100/760 | 39.22 200/760 | 67.38 300/760 | 90.86 400/760 | 104.292. Calculate the adsorption quantity n by dividing the volume of nitrogen by the molar volume of nitrogen at the experimental temperature and pressure. Assuming the molar volume of nitrogen is 22.4 L/mol at STP 0C and 1 atm , we can calculate n as follows:Relative Pressure P/P0 | n mol -------------------------|--------- 50/760 | 24.51/22400 100/760 | 39.22/22400 200/760 | 67.38/22400 300/760 | 90.86/22400 400/760 | 104.29/224003. Plot the BET adsorption isotherm by plotting 1/[n P0-P ] on the y-axis and P/P0 on the x-axis. Calculate the slope and intercept of the linear portion of the plot.4. Calculate the monolayer adsorption capacity n_m and the BET constant C using the slope s and intercept i of the linear plot:n_m = 1 / [ s/i - 1]C = 1 + [ s/i - 1]5. Calculate the specific surface area A using the monolayer adsorption capacity n_m and the cross-sectional area of the nitrogen molecule = 0.162 nm :A = [n_m * N_A * ] / mwhere N_A is Avogadro's number 6.022 x 10 mol and m is the mass of the sample 1 g .6. Report the specific surface area A in m/g or cm/g.Note: The actual calculations of the slope, intercept, n_m, C, and A require graphing software or a spreadsheet program to plot the data and perform linear regression. The provided data is not sufficient to provide a numerical answer without performing these calculations.
