Find the exit concentration and the conversion for a laminar-flow reactor under the following conditions using the segregated model: radius \(1 \mathrm{~cm}\), length \(500 \mathrm{~cm}\), mass flow rate \(0.1 \mathrm{~kg} / \mathrm{s}\), density \(1000 \mathrm{~kg} / \mathrm{m}^{3}\), and first-order rate constant \(k=0.1 \mathrm{~s}^{-1}\).

Also model the reactor

(a) as a plug-flow reactor and

(b) as a completely backmixed reactor.
