The number of correct statement/s from the following is __________. A. Larger the activation energy, smaller is the value of the rate constant. B. The higher is the activation energy, higher is the value of the temperature coefficient. C. At lower temperatures, increase in temperature causes more change in the value of k than at higher temperature. D. A plot of ln k vs 1/T is a straight line with slope equal to -E_a/R.
- 1
- 2
- 3
- 4
Correct answer: 4
Solution
All four statements are correct: A reflects the inverse relationship between activation energy and rate constant, B correctly describes the temperature coefficient's dependence on activation energy, C highlights the greater sensitivity of reaction rates to temperature changes at lower temperatures, and D accurately represents the Arrhenius equation's linear relationship.
