i need a solution on paper by hand writing

Q2/ The dynamic response of stirred tank bioreactor can be function Where C'concentration of exit subtance in deviation variable represented by (mol/L) and first C' c/ order transfer 2 C' T is concentration of feed substance in deviation variable (mol/L). Determine: l. 2. 3. The value of gain and time constant, its unit of the gain. What will the new steady Stae value if feed concentration change suddenly by 2 mol/L? About how long will it take to reach this new steady state?
