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
The rate of reaction is dependent on the concentration of reactants. The rate of a reaction decreases as time progresses. As a reaction progresses, the reactants are being turned into products, decreasing the concentration of the reactants, consequently, lowering the 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.
