The minimum energy required to allow a chemical reaction to proceed is termed as the 'threshold energy '. Chemical reactions with low activation energy are ________________?
Correct answer: C. Insensitive to temperature changes
- A. Always irreversible
- B. Mostly irreversible
- C. Insensitive to temperature changes
- D. Highly temperature sensitive
Explanation
From the Arrhenius equation, a smaller activation energy makes the rate constant change less when temperature changes. Such reactions are therefore relatively insensitive to temperature, although they may still be reversible or irreversible.
