Question

Which of these statements is not true about the chemical reaction rates

Answer 1

D is the correct answer. Chemical reaction rates won't always be constant, you can change the rate of a chemical reaction. Factors that affect chemical reaction rates would be temperature, the concentration (pressure) of the reactant, or just the general surface area (crushing a reactant would be an example). Solvent polarity can also decrease the rate of a chemical reaction. Therefore, A, B, and C are true, leaving D as the answer.

Answer 2

Here Is Your Answer

D. the reaction rates are always constant.

REASON: No chemical reaction is a perfect one. Every time slight variation can be seen in the chemical reactions.

So, reaction rates are not always constant.
