🔬 Deep Dive: The Reversible Symbol

A + B ⇌ C + D

The ⇌ symbol means the reaction is reversible

  • Forward reaction: Reactants (A + B) → Products (C + D)
  • Backward reaction: Products (C + D) → Reactants (A + B)
  • Both reactions happen at the same time
  • Changing conditions can favour one direction or the other
