Reaction is A-->B
is carried out adiabatically in a CSTR. The reaction is second order in A. The feed, which is equal molar in water (which contains the catalyst) and A, enters the reactor at a temperature of 52 C and a total volumetric flow rate of 10 dm3/min. The concentration of A entering the reactor is 4 molar. a) What is the reactor volume to achieve 80% conversion b) What conversion can be achieved in a 1000 dm3 CSTR?...

Note: Assume that the volumetric flow rate does not change with
reaction extent; when one reactant is in large excess, it is
reasonable to assume constant volumetric flow rate, especially for
liquid-phase reactions. You can only find KCbVr/Q that would yield
the desired 50% conversion in a single CSTR!
