6.7. The amount of (V) CO2 (273 K and 1.01 * 105 Pa)

6.7. The amount of (V) CO2 (273 K and 1.01 * 105 Pa) adsorbed per gram of coal at 273 K and various pressures is as follows:
P * 10–3, Pa 4.20 8.10 11.70 16.5 24.00
V * 10 ^ 6, m3 / g 12.73 21.20 26.4 32.20 38.60
Build the adsorption isotherm V = f (P) and p / V = f (P); describe the adsorption isotherm using the Langmuir equation; determine the adsorption value (m3 / g) at maximum adsorbent filling; determine the degree of filling of the adsorbent at a pressure of 2 * 10 ^ 4 Pa; determine at what gas pressure the degree of filling of the adsorbent is 0.4.
