The reversible elemental reaction AB is carried out in a CSTR reactor with heat exchanger. Pure A is introduced into the reactor.

a) Determine the temperatures at steady state. Specify what they are stable.

b) Determine the ignition and extinction feed temperature

c) If the heat exchanger fails, what is the temperature of the reactor at reach the new upper steady state?

d) What will be the necessary volume of an adiabatic PFR reactor to reach a conversion of 95% of the adiabatic equilibrium conversion?
