Please provide the matlab code with fsolver.

The following liquid-phase reactions are carried out isothermally in a 50 L PFR:

A+ 2BC +D , r1D = k1DCACB^2 , k1D = 0.25 L2 mol2 min1 2D+3A C + E , r2E = k2ECACD , k2E = 0.1 Lmol1 min1 B+ 2C D+ F , r3F = k3FCBCC^2 , k3F = 5.0 L2 mol2 min1 v0 =10 L/min CA0 =1.5 mol/L CB0 = 2.0 mol/L

Determine the effluent concentrations and conversion of A from a 50 L CSTR. What are the overall selectivity and overall yield for species D?
