Question

Which of the following changes to a reaction will always increase the rate constant for that reaction?

• A. Decreasing the temperature
• B. Increasing the temperature
• C. Increasing the concentration of the reactants
• D. Increasing the concentration of the catalyst

Hint:

Rate constant depends on temperature, not directly on concentration of reactants or catalysts.

Answer 1

The Correct Option is B

According to the Arrhenius equation $k = Ae^{-E_a/RT}$, increasing temperature increases the value of rate constant $k$ exponentially.
