If the time required to change the concentration of reactant to half its original value is independent of the initial concentration, the order of reaction is _______________?
Correct answer: B. One
- A. Zero
- B. One
- C. Two
- D. Three
Explanation
For a first-order reaction, the half-life is t₁/₂ = 0.693/k and contains no initial concentration term. Zero- and higher-order reactions have half-lives that depend on the starting concentration.
