Question$-$

Consider the set of liquid phase, elementary series reactions A $->$ B $->$ C to be carried out in a $10$ dm$3$ batch reactor. The reaction occurs at $300$K$,$ where k$1=0\mathrm{.}6$ h$-1$ and k$2=0\mathrm{.}25$ h$-1.$ The reaction starts with $4$ mol$/$dm$3$ pure A$.$

a$)$ Sketch a plot of the concentrations of each species versus time. You don$$t have to be exact, just give the shape of each curve.

b$)$ How long will it take to reach a maximum concentration of B$?$

c$)$ Assuming the answer to part $($b$)$ is $2\mathrm{.}5$ h $($this may or may not be correct$),$ calculate CA$,$ CB$,$ and CC at that time

Please provide solution with detailed steps. Thank you.
