(10 points) A basement (with volume V) in a residence is found to be contaminated with radon coming from the ground through the floor drains. The concentration of radon in the room is [Co] under steady-state conditions. The room behaves as a CSTR, and the decay of radon is a firstorder reaction with a decay rate constant of [k]. a. Now the condition changes: The source of radon is closed off but there is no ventilation. What is the equation that describes the concentration of radon in the basement with time [Ct]

![\mathbf{C_{Out} = C_o \ exp \Big [ - \Big ( \dfrac{1}{\dfrac{V}{Q} } + k \Big) t \Big ] }](/tpl/images/1097/3623/2fa15.png)
![\mathbf{C_{Out} = C_o \ exp \Big [ - \Big ( \dfrac{1}{\theta} + k \Big) t \Big ] }](/tpl/images/1097/3623/08411.png)
= concentration of the radon
= allowable radon concentration
