II.Concentration of products
III.Temperature

Question

Quizplus · Accepted Answer

The initial rate of a chemical reaction depends on the concentrations of the reactants because they must collide with each other in order to react. The higher the concentration, the more collisions are likely to occur, leading to a higher rate of reaction. It also depends on the temperature, as higher temperatures increase the kinetic energy of the molecules, leading to more frequent and energetic collisions. The concentration of products does not affect the initial rate of the reaction because products form only as the reaction proceeds.
