Answer

True

Work Step by Step

The chemical concentration in the tank is always dependent of the time. We presume, however, that a well-mixed mixture of water and chemicals exits the tank at a constant rate of $r_2$. This ensures that the chemical concentration in the mix that exits the tank is always constant. In other words, it is unaffected by the passage of time.
