(a) The mass of gas adsorbed, x, per unit mass of adsorbate, m, was measured at various pressures, p. A graph between log x/m and log p gives a straight line with slope equal to 0.5 and the intercept equal to 0.4771. Calculate the value of x/m at a pressure of 4 atm. (Given log 3 = 0.4771).
(b) Plot a graph of $q_e$ against time to show the kinetic performance of adsorption.
