Please help me express CP and CS with respect to CA$0$ and t$.$ someone on chegg previously answered with the equation as I've written on the bottom right part of the picture. but when I plotted it on excel, it resulted to a CP value exceeding the initial CA$0100$ mol$/$m$3$ and a negative CS value which should not be possible, please show me the correct CP$($t$)$ and CS$($t$)$ function to plot on the graph and show the complete integration process. Thanks a bunch. $($I have checked my excel function and cells thoroughly, there is no possibility of a mistype on the equation I entered to the cells$)$
