Cstr reaction rate
Web1. A first-order irreversible reaction: A B is taking place in a continuous stirred-tank reactor (CSTR) with a volumetric flow rate of 10 L/min. The reaction rate constant is 0.02 min^-1 and the feed concentration of A is 1 mol/L. What is the volume of the reactor required to achieve 90% conversion? WebThe CSTR is used for gas-liquid reaction when a gas reacts with a liquid in the liquid phase. The gas molecules move from the gas phase into the liquid phase. The gas is introduced …
