Reactor Cascade: Kymograph & Response Chart

Continuous manufacturing plants rarely run a single ideal plug-flow reactor — in practice they are built from a chain of well-mixed continuous stirred-tank reactors (CSTRs), and how that chain responds to a feed upset determines how quickly the line stabilises after startup and how a real deviation propagates downstream. This 2D companion solves the exact mass-balance ODEs for N CSTRs in series in real time — independently of the 3D version's rendering — and shows the result as genuinely two-dimensional data: a scrolling kymograph (tank index vs. time, colour = concentration) above a live time-response chart with the closed-form tanks-in-series curve drawn alongside the numerical integration for direct visual verification. Adjust the number of tanks to see the response sharpen from a single exponential lag toward the sharper, delayed step of an ideal plug-flow reactor.
