When measuring the adsorption of gaseous nitrogen on active carbon at 194.4K, the following data were obtained:
p•10-3, Pa……………….1.86 6.12 17.96 33.65 68.89
А•103, m3/kg…………..…5.06 14.27 23.61 32.56 40.83
A values are given for nitrogen under normal conditions.
Calculate the constants in the Langmuir equation and the specific surface area of activated carbon, assuming the density of gaseous nitrogen is 1.25 kg/m3, and the area occupied by one nitrogen molecule on the surface of the adsorbent is 0.16 nm2.
