Question

which of these statements is true about chemical reaction rates?

A. The reaction rates cannot decrease

B. the reaction rates cannot increase

C. The reaction rates can change

D. The reaction rates are always constant

Answer 1

Answer:

C) the reaction rates can change

Explanation:

Answer 2

The statement that is true about chemical reactions rates would be the capacity of reaction rates to change based on certain factors. The correct option would be C.

The rate of any chemical reaction is dependent on a host of factors which include:

• the temperature of the reaction
• the surface area of the reactants
• the presence of catalysts
• the concentration of reactants
• the physical state of reactants

Thus, chemical reaction rates are always changing depending on the factors above. In other words, they can increase or decrease as the case may be.
