Chemical Reactions: Summary

The answers to the ConcepTests are given below and will open in a separate window. 
Key points from this module:
  • Fractional conversion is the ratio of moles reacted to moles fed.
  • Yield, selectivity, and equilibrium constants can each be used to eliminate one degree of freedom for material balance systems.
  • The limiting reactant for a system serves as the basis for fractional conversion in many cases.
From studying this module, you should now be able to:
  • Use yield or selectivity to remove one degree of freedom.
  • Determine equilibrium constants.
  • Use fractional conversion in material balances.
  • Determine the limiting reactant for a system.
