Arrhenius equation shows the variation of ___________________ with temperature?
Correct answer: B. Rate constant
- A. Reaction rate
- B. Rate constant
- C. Energy of activation
- D. Frequency factor
Explanation
The Arrhenius relation, k = A exp(-Eₐ/RT), describes how the rate constant changes with temperature. Reaction rate also depends on reactant concentration, whereas Eₐ and A are treated as constants for a given reaction.
