As the time interval approaches zero the average and instantaneous rate become ?
Correct answer: C. Equal
- A. Negative
- B. Zero
- C. Equal
- D. Positive
Explanation
When considering reaction kinetics, the average rate of reaction over a given time interval is calculated as the change in concentration divided by the change in time. As the time interval becomes infinitesimally small, this average rate approaches the instantaneous rate, which is the rate at a specific point in time. Thus, the average and instantaneous rates become equal as the interval approaches zero. This is why Option C is correct. Options A and D are incorrect as they do not relate to the concept of average and instantaneous rates becoming equal. Option B is incorrect because the rates do not become zero; they converge to be equal.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
