Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.

1. For a fixed inlet flow rate of liquid into a tank whose outlet flow rate is proportional to volume in the tank, will the tank reach a steady state?
2. For a tank with a chemical reaction, if the feed concentration of reactant is higher than the starting concentration of reactant in the tank, what are the possible behaviors for the outlet concentration of reactant with time (decreasing, increase, exhibiting a maximum)?
