Which of the following statements regarding the determination of reaction rates is true?

Question

Quizplus · Accepted Answer

Reaction rates can be determined by measuring the amount of product formed or reactant consumed over time. This is typically done by measuring the concentration of the reactants or products at regular time intervals. The rate can then be calculated by dividing the change in concentration by the time interval.

Option B is incorrect because reaction rates are not solely dependent on stoichiometry. Other factors such as temperature, pressure, and catalysts can also affect reaction rates.

Option C is incorrect because reaction rates generally change over time as the concentration of reactants decreases or products increase.

Option D is incorrect because reaction rates can be affected by factors such as temperature, pressure, and the presence of catalysts.

Option E is also incorrect because the average rate of reaction can vary depending on the time interval over which it is calculated.
