A batch reactor when modeled in an unsteady state

for a non$-$elementary reaction results in the

following differential reaction:

$\frac{d{C}_A}{dt}=-2C_A^3+12C_A^2-20C_A+8\mathrm{.}5$

Where CA is the conWhere CA is the concentration of the reactant in the

reactor at time $$t$.$ The initial concentration on the

reactant CA$(0)=1$ mol$/$L$.$ Simulate the given

reaction model by using the Euler$$s numerical

method., till time t$=0\mathrm{.}5$ min to determine the

reactant concentration. Consider a step size of h$=0\mathrm{.}1$

and show all the five iterations. Explain the effect of

step size on the simulation performance.
