For adiabatic PFR A↔B (liquid) with pure A feed, the below temperature profile is observed. Why does the T plateau?

• 
  The reactant is completely reacted.

• 
  The reaction reaches equilibrium

• The reactor explodes

• B has a much higher heat capacity than A

For the same reactor+reaction, is the forward reaction exo or endothermic?

• Exothermic

• Endothermic

What does the R_B vs V look like?

• 
• 
• 
• 

Why does R_B initially increase before decreasing?

• The exothermic forward reaction drives the forward reaction faster

• 
  The reaction quickly reaches equilibrium

• 
  The volumetric flow rate expands than contracts

• The rising temperature drives the backward reaction faster

For endothermic adiabatic PFR, which graph could be its T vs V?

• 
• 
• 
• 

For Endothermic adiabatic PFR with a reaction at equilibrium, how does the T vs V graph change?

• 
• 
• 
• 

To increase the amount of product formed for equilibrium endothermic adiabatic PFR, you should add interstage coolers.

• True

• False
