A water treatment system has the following reactions. A+BkrkC The reaction rate for this equation is r=kf[A][B]kr[C] In this equation, A,B,C are three chemical species, r is the reaction rate, the kf and kr are the forward and reverse reaction rate constants. (1) write out the system of ordinary differential equations that describes the change of each species in this water treatment system (2) identify the dependent variables, and independent variables. Is the system closed? (3) Solve this system of ODEs with Matlba ode45 solver (https://www. mathworks.com/help/matlab/ref/ ode45. htm1.), and plot the concentration of each species over time. The initial concentration of reactants A, B and the product C are 0.25,0.2, and 0.3mol/L. The forward and reverse reaction rate constants kf and kr are 0.4mol1s1 and 0.2s1. (4) What is the concentration of each species when the reaction reaches to dynamic equilibrium? A water treatment system has the following reactions.
