28. Solving a chemistry problem

1. The table shows the dependence of the volume of substance (m3) adsorbed by 1 g of adsorbent at temperature T, K on the equilibrium partial pressure P(Pa).
According to the data provided:
1. Plot the adsorption isotherm V=f(P);
2. Plot the resulting isotherm in the coordinates of the Langmuir equation, determine the constants in the equation by graphical and analytical methods.
3. Determine the value of maximum adsorption when the degree of surface coverage is equal to 1.
4. Determine the adsorption value at pressure P1.
5. Plot the resulting isotherm in the coordinates of the Freundlich equation and determine the constants.
