Using Matlab, implement Eulers method to solve the ODE. Thanks!!

A mass balance for a chemical in a completely mixed reactor can be written as dc dt where V- volume (20 m2), c concentration (g/m2), F- feed rate, Q-flow rate (I m/min), and k a reaction rate (0.25 m /g2/min). Assume c(0)-0 and known feed rate, the time for the concentration reaches a stable level can be determined by solving the ODE. Consider the feed rate can be varied from 100g/min to 300 g/min, please examine the feed rate effects on the time for the concentration reaches a stable level and the stable level concentration
