What a catalyst work by:
Correct answer: B. Increasing the proportion of particles with energy greater than the activation
- A. Increasing the frequency of collisions
- B. Increasing the proportion of particles with energy greater than the activation
- C. Increasing the activation energy
- D. Increasing the concentration
Explanation
A catalyst primarily functions by increasing the proportion of particles with energy greater than the activation energy required for the reaction to occur, allowing the reaction to proceed at a faster rate. Thus, option B is the correct answer.

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.
