Question
Explain irreversible reaction.
✓
Answer
Irreversible reaction:
$i.$ Reactions which occur only in one direction, namely, from reactant to products are called irreversible reactions.
$ii.$ They proceed in only a single direction until one of the reactants is exhausted.
$iii.$ The direction in which an irreversible reaction occurs is indicated by an arrow $(\rightarrow )$ pointing towards the products in the chemical equation.
$\text { e.g. a. } C _{( s )}+ O _{2( g )} \xrightarrow{\text { Burn }} CO _{2( g )}$
$\text { b. } 2 KClO _{3( s )} \xrightarrow{\Delta} 2 KCl _{( s )}+3 O _{2( g )}$
