✅ Irreversible Reaction (अप्रतिवर्ती अभिक्रिया)

Jisme reaction sirf ek hi direction me hota hai — reactants → products.
Wapas products se reactants nahi bante ya bahut hi kam bante hain.

🔹 Features:

Reaction complete ho jata hai.

Equilibrium nahi banta.

Reactants poori tarah products me badal jate hain.

Ek hi direction ka arrow lagate hain:
A → B

🔹 Examples:

Burning reaction: C + O₂ → CO₂

Precipitation reaction: AgNO₃ + NaCl → AgCl↓ + NaNO₃

Neutralization: HCl + NaOH → NaCl + H₂O

✅ Reversible Reaction (प्रत्यावर्ती अभिक्रिया)

Jisme reaction dono direction me hota hai — reactants ⇌ products.
Products wapas reactants me convert ho sakte hain.

🔹 Features:

Reaction poora complete nahi hota, kuch reactants hamesha bachte hain.

Chemical equilibrium ban jata hai (forward = backward rate).

Dono direction ke arrows lagate hain:
A ⇌ B

🔹 Examples:

Haber process:
N₂ + 3H₂ ⇌ 2NH₃

Water dissociation:
H₂O ⇌ H⁺ + OH⁻

Esterification & hydrolysis:
CH₃COOH + C₂H₅OH ⇌ CH₃COOC₂H₅ + H
