( (i) Why does the flow rate of products out of a CSTR usually increase with increasing volume when the inlet flow rate remains constant? (a) Larger volumes increase the amount of time the fluid spends in the reactor on average. (b) Larger volumes increase the concentration of reactants. (C) Larger reactors are easier to mix (d) Larger reactors have better heat transfer characteristics, (10 points) Which change cannot cause an increase the rate constant (k)? (a) Raise temperature Page 1 of 3 (b) Use a better catalyst (o) Switch to a better reactor (d) All of the above can increase k (10 points)
