Definition of reversible reactions
Check what you remember
Read the wording for your board, then hide it and explain reversible reactions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Reactions in which the products can re-form the reactants, so the reaction never goes to completion and some reactant always remains.
