For the elementary Reaction in series, A$-$k$1->$R$-$K$2->$S where Ca$0=0\mathrm{.}5$; Cro $=$Cso $=0$ Determine the maximum concentration of R and when it is reached for the following cases; a$)$ k$1=0\mathrm{.}10/$min and k$2=0\mathrm{.}250/$min b$)$ k$1=$k$2=0\mathrm{.}10/$min c$)$ create a table showing the concentration of each species for a period of $5$ min at $1$ min interval
