The change in concentration of reactants or products per unit time is called rate of reaction. The rate of reaction:
Correct answer: B. Decreases as the reaction proceeds
- A. Increases as the reaction proceeds
- B. Decreases as the reaction proceeds
- C. Remains the same as the reaction proceeds
- D. May decrease or increase as the reaction proceeds
Explanation
As the reaction proceeds, the rate of reaction may decrease due to factors like the depletion of reactants or the accumulation of products. This can lead to fewer collisions between particles and a slower rate of reaction.

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.
