For most of the chemical reactions the rate of reaction
Correct answer: C. May increase or decrease during the reaction
- A. Increases as the reaction proceeds
- B. Decreases as the reaction proceeds
- C. May increase or decrease during the reaction
- D. Remains constant as the reaction proceeds
Explanation
The rate of a chemical reaction is the speed at which reactants are converted into products. In general, the rate of reaction may vary during the course of the reaction. Several factors can influence the rate, such as changes in concentration, temperature, or the presence of a catalyst.

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.
