Question:
Which of the following changes to a reaction will always increase the rate constant for that reaction?
Which of the following changes to a reaction will always increase the rate constant for that reaction?
Show Hint
Rate constant depends on temperature, not directly on concentration of reactants or catalysts.
Updated On: Dec 11, 2025
- Decreasing the temperature
- Increasing the temperature
- Increasing the concentration of the reactants
- Increasing the concentration of the catalyst
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
According to the Arrhenius equation $k = Ae^{-E_a/RT}$, increasing temperature increases the value of rate constant $k$ exponentially.
