1.5 Determine the volume of the CSTR if the conversion is 90%. List all assumptions. (17) {Total marks = 35} A solution of an ester, R-COOR', is to be hydrolysed with an excess of caustic soda solution. A stirred tank is to be used. The ester and caustic soda solutions flow separately into the tank at rates of 0,036 and 0,030 L/s with concentrations of 0.25 and 1.0 mol/L, respectively. The reaction is: R COOR' + NaOHR-COONa + R'OH The reaction is elementary with a rate constant of 0.024 L/mol.s at the operating temperature of the CSTR. Let A represent R-COOR', B represent NaOH, C represent R-COONa and D represent R'OH.
