Be sure to answer all parts. Nitrification is a biological process for removing NH3 from wastewater as NH4+: NH4++2O2NO3+2H++H2O The first-order rate constant is given as k1=0.47e0.095(T15C) where k1 is in day 1 and T is in C. If the initial concentration of NH3 is 3.0mol/m3, how long will it take to reduce the concentration to 0.94mol/m3 : (a) in the spring (T=20C) ? x ys (b) in the winter (T=10C) ? xys
