$(50$ points$)$ A batch reactor is being used to destory chemcial A with a initial conentration of $100m\frac{g}{L}.$ The reaction can be characterized by second order $)=(-k{C}^2,$ with a rate constant of $0\mathrm{.}0006\frac{L}{m}g-$min: Please apply the Euler's emthod, using a spreadsheet to calculate the concentration of chemical A after $1$ hours, using three time steps: $2$min,$1$min and also $0\mathrm{.}5$ min. Please compare the results and briefly explain why the results are different $($or the same$).$
