If the time required to complete a definite fraction of reaction varies inversely as the concentration of the reactants, then the order of reaction is________________?
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
For a second-order reaction, the time required for a fixed fractional conversion is proportional to 1/C₀. First-order reactions require the same fractional-conversion time regardless of C₀, so the order is 2.
