Consider the case of steady-state, simultaneous heat and mass transfer with chemical reaction as discussed in Section 5.5.1. The reaction is autocatalytic (self-catalyzed) and takes off at a temperature of \(75^{\circ} \mathrm{C}\). For the reactor and reaction data given below, pick an organic solvent that will insure safe, controllable, steady-state operation.

Reactor Length \(L=0.05 \mathrm{~m}\)

Reactor Temperature \(T_{o}=50^{\circ} \mathrm{C}\)

Diffusivity of A \(D_{a}=3 \times 10^{-5} \mathrm{~m}^{2} / \mathrm{s}\)

Rate Constant \(k^{\prime \prime}=0.15 \mathrm{~s}^{-1}\)

Heat of Reaction \(\Delta H=52,500 \mathrm{~J} / \mathrm{mol}\)

Initial Concentration \(c_{a o}=10 \mathrm{~mol} / \mathrm{m}^{3}\)
