First$-$order reaction of a given product in a fully mixed batch flow streams

It decomposes according to its kinetics:

Degradation Rate,

r $=$ dC$/$dt $=$ C $\text{'}=$k$$C

k : reaction rate constant $($day$^1)$

C: rules concentration $($mg$/$l$)$

In a performed experiment, the initial concentration in the sections at time t $=0$ was C$0=6\mathrm{.}4$ mg$/$L

It has been measured as and the rate constant is known to be k $=0\mathrm{.}3$ day$^1,$ which can be tested.

a$)$ What will be the concentration of your life after t $=2$ days? This initial value problem

You solve it with the improved Euler method in steps of $\backslash$Delta t $=0\mathrm{.}25$ days.

b$)$ Concentration$-$time showing the change in the reactor during the time interval t $=02$ days

Draw your curves. Add all necessary naming and formatting on the chart.

Do it appropriately.
