4. What are the advantages of a batch process?

  • Less flexible, suited to all types of products, low cost to build plants
  • Suited to high tonnage products, can operate for months at a time without shut-down, easily automated therefore smaller workforce
  • Cost effective for small quantities, low capital costs for plant, different products in the same vessel
  • Time consuming to clean reaction vessel, may require larger workforce, many products in one reaction vessel

5. How can you define polar molecules?

  • Only molecules with instantaneous dipoles
  • Only molecules with a permanent dipole
  • All molecules with dipoles
  • All molecules which have bonds
