What is Irreversible Reaction?
An irreversible reaction is a chemical reaction that proceeds in only one direction and goes to completion, converting essentially all reactants to products. The reverse reaction is negligible or impossible under the same conditions. In practice, a reaction is considered irreversible when its equilibrium constant (K) is very large (>10⁴) or when products are continuously removed (gas escapes, precipitate forms).

Combustion reactions (fuel + oxygen → CO₂ + H₂O). Acid-base neutralization (HCl + NaOH → NaCl + H₂O). Precipitation reactions (removing ion from solution). Explosive reactions. Industrial synthesis where high yield needed. Understanding one-way biological processes.
Conceptual classification — actual safety depends on specific reaction. Many irreversible reactions (combustion, explosions) are highly exothermic and potentially dangerous. Irreversibility used advantageously in chemical trapping and scavenging reactions.
