A tubular reactor has been sized to obtain 98% conversion and to process 0.03 m³/s. The reaction is a first-order irreversible isomerization. The reactor is 3 m long, with a cross-sectional area of 25 dm². After being built, a pulse tracer test on the reactor gave the following data: t_m = 10 s an =² = 65 s². What conversion can be expected in the real reactor?
