Half life period of a chemical reaction is proportional to CA0 -1, if the reaction is of _______________ order?
Correct answer: C. Second
- A. First
- B. Zero
- C. Second
- D. Third
Explanation
For a second-order reaction, the half-life is t₁/₂ = 1/(kC_A0), so it is inversely proportional to the initial concentration. This gives the dependence C_A0⁻¹ and identifies second order.
