Can you please solve it with step by step explanation?

{3} (5 points} The chemical reaction from solution A to B takes into two steps. The governing equations are: d'gh = r1{CAD CA1) kCAl, Big? 4-1031 + coal, dodge Tlma, _ CA2) 3601421 g? rimsl 032) + kcag, where CAD 2 concentration of A at the inlet of the rst reactor, CA1 2 concentration of A at the outlet of the rst reactor (and inlet of the second), CA; 2 concentration of A at the outlet of the second reactor, OBI 2 concentration of B at the outlet of the rst reactor [and inlet of the second), CB: : concentration of B outlet of the second reactor. Use k = [1.12, time domain t E (D, 1}, h 2 U4, '1" = 1,15. Assume that, at the starting time, CA0 : 2i], and all other dependent variables are zero. Solve with Euler's method
