The reaction of compounds A and B, in highly diluted aqueous media, has the following stoichiometry and reaction rate: A(a q)+B(a q) \rightarrow R(a q) \quad-r_{A}=2.25 C_{A} C_{B} \quad \text

{ mol } \cdot \min ^{-1} \cdot L^{-1} Two streams containing the reactants (v4 = 25 L min-1, CA.0 = 0.04 mol L-1; and v3 =25 L min-1, CB,0= 2 mol L-1) are mixed and supplied to one continuous stirred tank reactor.Calculate: O Reactor volume needed to achieve a fractional conversion of XA = 0.9. ii) Concentration of A, B and Rat the reactor outlet. (iii) Maximum fractional conversion of A achieved if we split the overall reactor volume into four identical continuous stirred tank reactor in series.[3 marks] Under the same processing conditions (v4, VR, V), we now use a tubular reactor with an overall length of 10 m (NOTE: Take V=50 L if previous questions were not answered). Calculate, (iv) Maximum fractional conversion of A that can be achieved (v) Distance from the reactor entrance at which the reaction rate falls below 0.05 mol min1 L1.
