0731. Solving a chemistry problem

1. When studying the adsorption of gaseous krypton (at 77.5 K) on a catalyst:
P, Pa 13.22 23.99 49.13 75.70 91.22
A*103, m3/kg 1.27 1.5 1.76 1.9 1.98
The A values for krypton are given under normal conditions. Check whether the experimental data can be described by the BET isotherm equation. Determine the constants of the BET equation and the specific surface area of the catalyst, assuming that one krypton atom occupies an area of 0.195 nm2, Ps = 342.6 Pa, and the density of krypton is 3.74 kg/m3.
