High traffic contributes to driving stress, while in chemistry, factors like concentration, pressure, surface area, and temperature are crucial for reaction speeds. Increased concentration and pressure enhance collision frequency, smaller particles improve surface area, and higher temperatures accelerate particle movement, all contributing to faster reactions.

It explains the dissociation of these ionic compounds into individual ions when dissolved in water, contrasting this with nonionic compounds, such as sucrose, which do not dissociate. The importance of understanding these processes for effective winter road maintenance is also highlighted.
