4. The parallel homogeneous reactions A+Br1C,r1=k1CACB,Ar2D,r2=k2CA occur in a steady-state plug flow reactor where v is uniform, v=v0. The reactor feed contains only A and B. (b). Divide mass balance for A by that for B to eliminate V and integrate the resulting differential equation to obtain CA=CA0CB0+CB+k1k2ln(CB0CB) 4.
