The elementary, liquid-phase, irreversible reaction a + b  c is to be carried out in a steady-state flow reactor. two reactors are available, an 800 dm 3 pfr that can only be operated at 300 k and a 200 dm 3 cstr that can be operated at 350 k. two streams (each with a flow rate of 5 dm 3 /min and equal concentrations of a and b at 2 mol/ dm 3 ) mix to form a single feed stream that enters the reactor. which of the two reactors will yield the highest conversion? the reaction has an activation energy of 85,000 j/mol-k and a rate constant of 0.07 dm 3 /mol-min at 300 k.
