can somebody help with these questions as soon as possible please

Part II - Introduction to Biological Wastewater Treatment Problem 2 (10 points) A very high dose of ammonia is added into an aerobic laboratory chemostat containing a mixed culture of ammonia oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB). The chemostat is continuously fed a solution containing an abundance of the electron acceptor (dissolved oxygen), ammonia and nitrite (each at its Smin level), and all other nutrients necessary for the growth of AOB and NOB. In light of the energy production for AOB vs that of NOB which biological population will remain after a long-term operation if one assumes equal population sizes at the start of the experiment? Explain. Part III - Mass Balance Analysis and Reactor Kinetics Problem 3 (20 points) Consider the following reaction: 2A = C-stoichiometric reaction A+A elementary reaction a) What would the rate law for this reaction be? b) If the rate loss of A is 2x10mole/L-sec, what is the rate of appearance of Aassuming that (l) the reaction proceeds in a constant volume completely mixed batch reactor (dilute aqueous reaction). (ii) Cao = 2*10-3 M, and (ii) Cco = 0.5*103 M C? a) Derive an expression for the concentration of C as a function of the concentration of A. (5 points). b) Derive an expression for the concentration of A and C as a function of time (10 points)
