⭕ A. Increases
⭕ B. Decreases
⭕ C. Remains unaffected
⭕ D. None of the above
📚 Explanation:
During chlorination, if the temperature of water increases, the death rate of bacteria also increases.
🔹 Higher temperature enhances the chemical reaction rate between chlorine and bacterial cells.
🔹 This leads to faster destruction of pathogens and improved disinfection efficiency.
Reasoning:
✔ Reaction rate ↑ with temperature ↑ ✔ Faster penetration of chlorine into microorganisms ✔ Quick inactivation of harmful bacteria
During chlorination, if the temperature of water increases, the death rate of bacteria also increases.
🔹 Higher temperature enhances the chemical reaction rate between chlorine and bacterial cells.
🔹 This leads to faster destruction of pathogens and improved disinfection efficiency.
Reasoning:
✔ Reaction rate ↑ with temperature ↑ ✔ Faster penetration of chlorine into microorganisms ✔ Quick inactivation of harmful bacteria
👉 Therefore, the correct answer is: A. Increases
Key Points on Chlorination & Temperature:
- Temperature ↑ → Reaction rate ↑
- Faster bacterial death: Higher temperature improves chlorine efficiency.
- Important in water treatment: Temperature affects disinfection kinetics.
