The order of B.O.D. reaction is:
The order of B.O.D. reaction is:
Show Hint
BOD degradation follows first-order kinetics because oxygen depletion depends on remaining organic matter.

- \( 0 \)
- \( 1 \)
- \( 2 \)
- \( 0.5 \)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: The biochemical oxygen demand (BOD) reaction follows a first-order kinetics:
\[
\frac{dL}{dt} = -kL
\]
where:
- \( L \) is the remaining oxygen demand,
- \( k \) is the rate constant.
Step 2: The first-order reaction implies that the rate depends only on the concentration of organic matter.
Thus, the correct answer is (B) 1.
