Arrhenius constant depends upon _ of reacting substance.

Correct answer: D. Collision frequency

  • A. Concentration
  • B. Pressure
  • C. Volume
  • D. Collision frequency

Explanation

Option D is correct the higher the collision frequency between reacting molecules, the greater the probability of successful collisions leading to product formation. Therefore, the Arrhenius constant (A) is influenced by the frequency of molecular 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.
