The following reaction takes place in two reactions: A > B, where r=kCa, k=1(1/sec). Compare the reactors when 1 reactor is a BSTR with V=10m^3 and the other is a CSTR with V=10m^3 &Q=10m^3/s. Assume Ca(t=0)=Ca0=10mol/m^3. a) Solve for Ca(t) and Xa(t) for the BSTR and the CSTR. b) Sketch Ca(t) for each together on the same graph. Sketch Xa(t) together on a new graph. c) Explain which reactor yields the greater ultimate conversion. Why? d) Can any part of the system (V,Q,k) be changed to alter the answer to (b)? Why or why not?
