Reaction A -> 2B is taking place in a steady state plug flow reactor of a volume (‘V’) of 16 L. The volumetric flow rate of the feeds in and out are equivalent (v = vo) at 4.0 L/min. With a rate law of –rA=kCA2 and inlet and outlet concentrations of 5mol/L and 1 mol/L, what is the value of the rate constant, ‘k’, (L/min*mol) for the reaction? Please provide your answer to the first decimal place.
