Which of the following leads to an increase in the rate of a chemical reaction?
A) increased temperature
B) large particle size
C) lack of catalysts
D) decreased temperature
E) few particles

Question

Quizplus · Accepted Answer

Increasing temperature increases the kinetic energy of the particles, which leads to more collisions and an increased reaction rate. Conversely, decreasing temperature slows down the reaction rate. Large particle size and few particles have no effect on the rate of the reaction, while lack of catalysts actually slows down the reaction.
