1. In a series of equal volume isothermal CSTRs (continuous stirred tank reactors) the following first order parallelreactions in liquid phase are carried out. k1=0.1s1k2=0.05s1 The inlet concentration of A is 0.75kmol/m3. The volume of each reactor is 0.5m3, the volumetric flow rate of the fluid entering the reactors is constant at 0.225m3/s. Calculate the number of reactors to achieve a conversion of A of 90%. Hint: 'Assume steady state operation and develop the model in Finite Difference Equation form
