An isothermic reaction is carried out adiabatically and the CSTR reactor design algorithm is shown as below:
The reaction is second order in A. The feed which is equimolar in a solvent and A, and its enters the reactor at a total volumetric flow rate, v0 of 10 dm3/min with the initial concentration of A being 4 M. The rate constant, k given as 0.1 dm3/mol.min at 380 K. Determine the conversion can be achieved in 600 dm3 CSTR by using the following methods:
a) Graphically
b) False position method with initial guesses of Xl =0.6 and Xu =0.9
c) Secant method with initial estimates of X-1 = 0.6 and X0, =0.9
Iterate until the approximate error falls below 1 %. Find the absolute relative approximate error at the end of each iteration.
in false position method check f(a)*f(b) after every step. If the product is < 0, then the next root will lie between a and b
