I need to solve this using matlab.
2) Chemical-kinetics problems often lead to sets of coupled,firsorder ODEs. For example, consider the reaction network Assuming a first-order reaction-rate expression for each transformation, material balances for each species lead to the following set of ODEs dt dB dt dC dt Solve the set of ODE given above, with k,-5, k2-2, k,-1, A(0) concentrations versus time graph 1, B(0)-C-(0)-0.

Chemical Kinetics
At pH > 4, the oxidation of Fe2+ in solution can be represented by the overall reaction For this reaction, the empirical rate law (Langmuir, 1997) is k+ indicates that this is the rate constant in the forward direction. For this reaction, at 20degreec, k+ = 1.2 X 10^-11 mol^2 bar^1^-1. Under atmospheric conditions, Po_2 = 0.2 bar. Given that Fe^2+ in solution = 1 X 10^-3 mole/L, calculate the reaction rate at pH = 5 and pH...
