Question

Question 3 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 0036 and 0 020 Ls' with concentrations of 0 25 and 10 mol L !respectively The reaction is R-COOR' + NaOH --R-COONa+R'OH The reaction is second order with a rate constant of 0 024 L mol's' at the operating temperature of the CSTR Determine the volume of the CSTR if the conversion is 90% List all assumptions [Q3 total = 30]

Answer 1

Given, Here - ester cawtic soda 2 v- 0.036 /s Vo = 0.020 HS Cio=0.25 mol - 10 moto i Ke 0.024 molis X = org excess, reactant. since caustre soda is This ester is omiting For CSTR СръХА Scho (lexosh KCR -o X Come and the AJE CO36 y. oond tos (0.25 miles (.1-0932 .25 mg *99, 1, X 2 , 5 X6 • - 0.024 x(0.25,2x0,12 V = 540 L
