Integrating with C, = CA0 at t = 0, we have

Zero-order (5-14)
A plot of the concentration of A as a function of time will be linear (Figure
'5-3) with slope (- k) for a zero-order reaction carried out in a constant-volume
batch reactor.

If the reaction is first order (Figure 5-4), integration of the combined
mole balance and the rate law

with the limit C, = C,, at t = 0 gives
