What is the order of a chemical reaction whose rate is deter-mined by the variation of one concentration term only ?
Correct answer: B. First
- A. Zero
- B. First
- C. Second
- D. Third
Explanation
If the rate depends on only one concentration raised to the first power, the reaction is first order. A zero-order rate is independent of concentration, while higher orders require a higher power or combined concentration dependence.
