Reversible Reaction
A reaction that can proceed in both the forward and reverse directions under the same conditions.
Formula / equation
A + B ⇌ C + D
Unit
Dimensionless
In depth
Reversible reactions never go to completion; instead they settle at a dynamic equilibrium where forward and reverse rates are equal. The position of that equilibrium can be shifted by changing concentration, pressure or temperature, which is the basis of industrial yield optimisation.
Examples in the real world
N₂ + 3H₂ ⇌ 2NH₃ in the Haber process; the hydration of anhydrous copper sulfate.
