141. Solving a chemistry problem

The amount (V) of CO (273 K and 1.01 * 10 ^ 5 Pa) adsorbed by 1 g of coal at 273 K and various pressures is as follows:
P * 10–3, Pa 9.8 24.2 41.3 60.0 72.5
V * 106, m3 / g 2.53 5.57 8.43 11.20 12.85
Plot the adsorption isotherm V = f (P) and p / V = f (P); describe the adsorption isotherm using the Langmuir equation; determine the amount of adsorption (m3 / g) at the maximum filling of the adsorbent, determine the degree of filling of the adsorbent at a pressure of 5.5 * 10 ^ 4 Pa; Determine at what gas pressure the degree of filling of the adsorbent will be 0.3.
