(a) Adiabatic Operation. Plot X, X,, P, T, and the rate of disappearance as a function of V up to
V = 40 dm³. Explain why the curves look the way they do.
(b) Vary the ratio of inerts to A (0≤0, <10) and the entering temperature, and describe what you find.
(c) Plot the heat that must be removed along the reactor (Q vs. V) to maintain isothermal operation.
Part (c) is "C" level of difficulty.
We will continue this problem in Chapter 12.
