Question of the Week

Operating conditions for a plug-flow reactor for the elementary liquid-phase reaction A+B →R are as follows:

        CAO = 0.10 kmol/m³
        CB  = 0.10 Kmol/m³
         V  = 0.50 m³
         q = 0.20 m³/min 
         CA (at exit) = 0.40 kmol/m³

The space time (min) for this reactor is most nearly:

The correct answer is D (2.5)
