Extracted text: As a new engineer in a company XZ, your boss has assigned you a project that is related to the removal of pollutant A in pharmaceutical wastewater. To achieve the objective of the project, you had conducted the experiment in a batch mode. The initial concentration of the pollutant A was set at 2.5 mol/dm³. The remaining concentration of the pollutant was identified using a UV-Vis. The complete experimental data obtained is tabulated in Table 1. Table 1 t (hr) 5 10 15 20 25 А + 1.95 1.65 1.15 0.88 0.60 (mol/dm') + Determine the removal rate of pollutant A by using numerical method. а. b. Is the removal time of 25 hours sufficiently enough to remove the pollutant A more than 90%? Justify your answer by using answer from (a).
