(b) The kinetics of a system are extremely important when sizing various unit operations. Adsorption tanks or columns are no different. The data presented in the table below was obtained by the students when they investigated the kinetics the system. Evaluate which reaction kinetics model between the Pseudo First order and Pseudo Second order best describes the data. In these studies, the initial dye concentration was 25 mg/L and 0.05 g of SBE adsorbent was added to 100 mL of solution. (12)

NB. All relevant graphs and constants obtained should be reported.
