Which statement correctly describes reaction rates?

Question

Quizplus · Accepted Answer

Decreasing the reactant concentration will decrease the reaction rate because there will be fewer particles to collide and react with each other. This means that the frequency of collisions will be lower, resulting in a slower reaction rate. Increasing temperature, on the other hand, will typically increase the reaction rate because the particles will have more kinetic energy and will collide more frequently and with greater energy. Therefore, option B is incorrect. Option C is also incorrect because increasing the temperature typically increases the reaction rate instead of decreasing it. Option D is incorrect because both reactant concentration and temperature can significantly impact reaction rates.
