6.9. The amount of (V) NH3 (273 K and 1.01 * 105 Pa)

6.9. The amount of (V) NH3 (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 10.5 21.6 42.7 65.6 85.2
V * 106, m3 / g 60.4 90.3 115.7 127.0 132.4
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 5 * 104 Pa; determine at what gas pressure the degree of filling of the adsorbent is 0.4.
