Thermal Effects in Chemical Reactions: Summary
Key points from this module:
- An inert affects the adiabatic equilibrium temperature for a chemical reaction. It lowers the temperature for an exothermic reaction and raises the temperature for an endothermic reaction.
- Increasing the temperature decreases equilibrium conversion for an exothermic reaction.
- Increasing the temperature increases equilibrium conversion for an endothermic reaction.
- An isothermal reactor has a higher equilibrium conversion than an adiabatic reactor for both exothermic and endothermic reactions.
From studying this module, you should now be able to:
- Calculate the exit temperature from a chemical reactor if the exit conversion is known.
- Calculate the equilibrium conversion in an adiabatic reactor.
- Calculate the adiabatic equilibrium temperature for a chemical reaction.
- Explain what effect adding an inert will have on the adiabatic temperature for either an endothermic or exothermic reaction.
- Calculate the heat that must be removed to keep a reactor isothermal, given the exit conversion from the reactor.
