Arrhenius Constant "A" depends upon:
Correct answer: D. Collision frequency of reacting substance
- A. All of these
- B. Universal gas constant "R"
- C. Activation energy
- D. Collision frequency of reacting substance
Explanation
In the Arrhenius equation, (k = rate constant, A = pre-exponential factor, Ea = activation energy, R = universal gas constant, T = temperature) The pre-exponential factor, also known as the frequency factor depends upon the frequency of collisions.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
