P5-15 The gaseous reaction AB has a unimolecular reaction rate constant of 0.0015 min at
80°F. This reaction is to be carried out in parallel tubes 10 ft long and I in. inside diam-
eter, under a pressure of 132 psig at 260°F. A production rate of 1000 lb/h of B is
required. Assuming an activation energy of 25,000 cal/mol, how many tubes are needed if
the conversion of A is to be 90%? Assume perfect gas laws. A and B each have molecular
weights of 58. Source: From California Professional Engineers' Exam.
P5-16 (a) The irreversible elementary reaction 2A B takes place in the gas phase in an isothermal tubular
(plug-flow) reactor. Reactant A and a diluent Care fed in equimolar ratio, and conversion of A is
80%. If the molar feed rate of A is cut in half, what is the conversion of A assuming that the feed
rate of C is left unchanged? Assume ideal behavior and that the reactor temperature remains
unchanged. What was the point of this problem? Source: From California Professional Engineers'
