Hard
A→B (first-order, adiabatic CSTR) with a design chart of XA vs. T for various rate values. CA0=5 mol/m³, FA0=100 mol/s, and T=350+25XA (energy balance). For XA=0.80, the CSTR volume (m³), rounded to 1 decimal place, is
8 m^3(± 0.3 accepted)
Explanation
At XA=0.8, T=350+25(0.8)=370K, which the chart shows lying on the rate=10 mol/m³/s curve. V=FA0·XA/(−rA)=100×0.8/10=8.0 m³.
