Reactor Rate and Conversion Versus Space Velocity

The irreversible reaction A → B takes place in an isothermal plug flow reactor (PFR). The rate of reaction and the fractional conversion are plotted versus space velocity (entering volumetric flow rate/reactor volume). As space velocity increases, the time available for reaction decreases. Use sliders to vary the dimensionless "rate constant" and dimensionless "feed concentration". Select the "reaction order" with buttons. Conversion is low for smaller space velocities, regardless of the order of reaction, and for a first-order reaction, conversion is independent of feed concentration.
