🔬 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

Practice questions for Reversible Reactions

What does the symbol ⇌ mean when used in a chemical equation?

  • A. The reaction is very fast
  • B. The reaction produces a gas
  • C. The reaction can proceed in both the forward and backward directions
  • D. The reaction requires a catalyst
